JavaScript - Javascript Scrolling Gallery Help
Hi Guys,
I've been progressing along ok onthe CSS side of things but am having some trouble on the javascript side of things. I've decided to jazz a site up with a scrolling gallery from a template i'm using but unfortunately I don't know how to get the main image to change on a click of the smaller one? can anybody please help a brother out! here's the site template - http://dev.jeffking.co.uk/index.html All i'm after is the big main image to change to the same (larger) image of the smaller one in the scrollbar below the main frame. Many thanks! Similar TutorialsHello, Currently I'm looking at smooth scrolling Js scripts for thumb images which can be altered to accomodate needs. I found one here that has some desirable effects but has no navi buttons. Would it be sensible to alter and point the hovering mouse scroll function to buttons, or would it be a better idea to keep looking for exactly the right script? The 2 identical scrollers on this page are the look I want but these are flash; http://area.autodesk.com/ ps: I've no experience of Js but can pick things up pretty quickly. Hey all, Effectively what I want is a table displaying 20 thumbnails and above the table to be a large image. When a user clicks a thumbnail I want a relative image to be displayed above. Now obviously I can just set this to reload the page and load the relative image in its space but I was wondering if there was a way of doing this without having to reload the whole page each time. I also want to avoid Iframes as I want this to be as cross-compatible as possible. Thanks all. Dear Friends, I have a javascript image gallery in my website.. it is working Good.. But now i have some problem... i have to get the Loaded image url. i need users to post comments about that image. So i have to get the URL or name of image. This is needed in a text input field... So please see the code of gallery and help me.. The code is below.. Or Check it here http://www.home-palettes.com/gallery.html Code: //add thickbox to href elements that have a class of .thickbox

http://www.muffettandsons.com/specproductstest.html Follow the link above and click on the pic to the right to open the pop up image gallery. For some reason the thumbs do not appear in the left preview pane until a rollover of the preview pane slide bar. This only occurs in IE. Firefox and Chrome both show the thumbs when opened and work just fine. Any help would be greatly appreciated... Thanks Hi guys... for my first project, me and my friend (who is a graphic artist) will make his portfolio site... I'm planning a single page website, where on the center part there will be a 960 x 500 gallery. He already have 50+ drawings ready for his gallery, the concept in my mind is for him to categorize his drawings, then those categories will become some sort of tabs, then the whole galley will occupy the said dimension above. I'm planning to display maybe around 5 thumbnails per tab, I want to make it sort of like a slide show gallery, it will also have a previous and next button then upon clicking the thumbnail, a full version of that image will pop-up but not in a new window, it will be within that page and will have a close button to go back to the main page... most portfolio sites I've seen were using this kind of preview in their gallery... How can I do this things/effect, I've read somewhere that this can be done using AJAX... Sorry if I'm not clear on what I've said as I'm still a newbie specially with this XML and AJAX thing... Thanks for having the time reading my post, looking forward for your help... ^_^ Hi, Wonder if you could help I have a js issue with i.e, my gallery works fine in ff but not in ie. Any ideas heres the link http://www.sparekeys.org.uk/ Hello everyone, Sorry if this has been asked before but I couldn't fine one... I basically want a slider for my website so the user can click on the arrows overlaid onto of the image, and it will slide the image to the next one. There will need to be lots on the page at one time as it is a gallery theme website, so can't be processor hungry! Can someone point me in the right direction please? I have found several but the buttons are always on the outside of the image div. And also do not work well with more than one on the page at one time? Also... Is there a way to snap the scrolling so the mouse wheel is scrolled down, and then the page snaps to the next 'projectcontainter' div on my website? iScroll I was told is used for this buy I can't seem to find out where or how. I am new to all this javascript so any help would be appreciated! Website is located at: www.jb-design.me/marchupdate/ Thanks so much! Hi! I've been working on a javascript photo gallery on my talent agency's website. I'm running into a bit of trouble with two things... First off, i would like it that when the mouse is removed from the thumbnail, that the image the mouse was last on would remain on screen but the thumbnail wouldnt change back. Also, i cant figure out how to make it that when an image is being displayed, the photographer and makeup artist information could also be seen under the picture. Any help in this would be GREATLY appreciated! A sample of one of the pages this is being used on is the following: http://www.cyanidenation.com/dakygallery.html The code I'm using is the following: Code: <!--
function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}
function MM_swapImgRestore() { //v3.0
var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
}
function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}
function MM_swapImage() { //v3.0
var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}
}

Thanks for the help! Not sure where to even start here. I am trying to build a a small JavaScript image gallery. As you can see in the jpeg image at the link provided, i want the user to be able to change the large image by clicking on the small thumbnails. The thumbnails will also have a roll over where they enlarge slightly. Complicated? I'm not a javascript expert, but i know enough by editing existing code and have saved a bunch of code i've modified. I've googled for javascript image galleries and looked through them but no success... I can understand the clicking on a thumbnail to change the larger image but what gets me is having the thumbnail on top of the larger..as well having a still image at the top left....some sorta layering? anyway some sorta help to get me started would be very helpful... http://www.rossow-web.com/test/RCC_Mockup.jpg thanks! Hello. I am having trouble with a simple image gallery with navigational buttons including "first", "next", "previous", and "last"; and making a drop-down archive menu. 1. For the most part, the image gallery works. The problem is that when a user clicks on "next", and then "prev", the last image is not displayed. On the other hand, if a user clicks "prev", and then "next" the last image is displayed(works normally). 2. The way I am displaying the last image, the function last(), is not efficient. It simply refreshes the page in order to display the last image. Basic overview: The images follow a simple standard: page1, page2, page3,...page64; they are in a subfolder "img". The function changeImage() changes the image from the prev, to the next. The image gallery displays the last image in the gallery; when a user clicks on 'prev' it goes to the previous image, and go to the next image when clicked on 'next'. If the current image is the last image, and the user clicks on 'next', it goes to the very first image. Here is the code (in the <HEAD> tags): Code: <script language="JavaScript"><!--
which_image_loaded = -1;
NUMBER_OF_IMAGES = 64;
current_comic = 0;
ImageNames = new Array;
ImageNames.length = NUMBER_OF_IMAGES - 1;
for (counter = 0; counter < NUMBER_OF_IMAGES; counter++){
file_number = counter + 1;
filename = ("../img/page" + file_number + ".png");
ImageNames[counter] = filename;
}
function changeImage(direction) {
which_image_loaded += direction;
current_comic = which_image_loaded + 1;
if (which_image_loaded < 0)
which_image_loaded = NUMBER_OF_IMAGES - 1;
if (which_image_loaded == NUMBER_OF_IMAGES)
which_image_loaded = 0;
if(current_comic <= 0){
which_image_loaded--;
}
document.myimage.src = ImageNames[which_image_loaded];
}
function first(){
which_image_loaded = 0;
current_comic = 1;
document.myimage.src = ImageNames[0];
}
function last(){
window.location='http://www.bearoncampus.com';
}
and in the <BODY> tags Code: <img src="img/page64.png" alt="New comic not available." name="myimage" width="725" height="275"> <form> <input type="button" value="FIRST" onClick="first()"/> <input type="button" value="PREV" onClick='changeImage(-1);' /> <input type="button" value="NEXT" onClick='changeImage(1);' /> <input type="button" value="LAST" onclick="last()" /> </form> My guess is the code is not working properly due to the initial values of the counter. Last, is there a way to display the current image "myimage.src" using a dropdown menu with each option value as each image? I have done this with window.location, but this only redirects to the image location. Much thanks. Any help is greatly appreciated. Ok if you visit Event Flooring Gallery you will see that i have a js gallery with a number of images. The gallery itself is loading the images fine and you can click the buttons to seperate the images into their correct products. My problem is when i click the images the big version of the image should load but instead it gives me an error that the image may not exist or the path may be incorrect but ive checked on my laptop and every link is perfect its working fine on my laptop??? Any ideas?? Would it have anything to do with the images themselves as in they are each around 2mb or more each? Hi I am using the css image gallery I got from: http://www.dynamicdrive.com/style/cs...image-gallery/ I want to change the behaviour, currently an image is enlarged when a user hovers over the link/thumbail. I would like to change it so that the main image is instead shown onclick of the thumbnail, and remains enlarged until another click. Is this possible using some javascript? I hired psd2html.com to code my portfolio website because I had no idea where to start. They designed a specific gallery for me and I don't like it anymore, and it's the last thing holding my back from making my portfolio live. Here is what it looks like right now: http://www.mustlovepink.com/index2.html I attached an image that describes what I would like the gallery to look like. I don't think it's all that different, but the code is honestly such a mess that I need someone to help me with it. I don't even know where to begin If you need more information in order to tell me, feel free to let me know. I really want to get this thing figured out. Hi! I'm wondering if somebody here could help me please. I'm trying to develope the image slideshow using PHP and JavaScript. The idea is that the PHP file gets random images from the folder, i'm using session to prevent repeating the same image and then JavaScript generates the fade slideshow using that PHP file. I've come up with the solution to use two img tags in the HTML page, so JavaScript then swap them around and play with opacity, but unfortunately couldn't make it work. Everything I have tried in JavaScript didn't work properly. I'd be grateful for any help and advice guys. Thank you. My PHP code: PHP Code: <?php class images { var $images = Array(); var $imgDir = 'images/'; function getImages() { $images = Array(); if ($dir = opendir($this->imgDir)) { while(($file = readdir($dir)) !== false) { if(preg_match('#(\.jpg$)|(\.png$)|(\.jpeg$)|(\.gif$)#i', $file)) $images[] = $file; } closedir($dir); } return $images; } function getNextImage() { if (($images = $this->getImages()) !== false) { session_start(); if (!isset($_SESSION['image'], $images[$_SESSION['image']])) { $index = mt_rand(0, count($images)-1); } else { $index = $_SESSION['image'] == count($images)-1 ? 0 : $_SESSION['image']+1; } $_SESSION['image'] = $index; return $images[$index]; } return false; } function outputImage() { if (($file = $this->getNextImage()) !== false) { header('Cache-Control: no-cache, must-revalidate'); // HTTP/1.1 header('Expires: Wed, 9 Dec 1981 07:00:00 GMT'); // Date in the past header('Content-type: image/jpg'); readfile($this->imgDir.$file); exit(); } } } $img = new images(); $img->outputImage(); ?> My HTML page: Code: <html> <head> <title>Images</title> <link rel="stylesheet" type="text/css" href="css/style.css" /> <script type="text/javascript" src="javascript/slideshow2.js" language="javascript"></script> </head> <body onload="startSlideShow();"> <h1>Images</h1> <div id="imageWrap"> <div id="images"> <img id="sampleImgFade" src="images.php" alt="images" style="filter:progid:DXImageTransform.Microsoft.alpha(opacity=0);-moz-opacity:0;-khtml-opacity:0;" width="800" height="600" onload="coverLoaded(this);" /> <img id="sampleImg" src="images.php" width="800" height="600" alt="images" onload="mainLoaded();" /> </div> </div> </body> </html> CSS code: Code: #imageWrap {

Hi - I don't know much about javascript, html, or web development. I have this javascript on my page (that is an iframe). <script type="text/javascript"> var site = 'http://' + 'localParameter("site_address")' <!-- window.location = site //--> </script> Note: site_address is a parameter that's passed to the page when loaded. Now, I need to make this iframe scroll down by like 50 pixels once the page is loaded. How can I do this? Thanks Hi, I'm attempting to add the following functionality to my site. Essentially, two images are displayed with a link "View More". The user clicks "View More" and the two images are replaced by two new images. This can be repeated as required. It's a basic form of slideshow I guess, but after some googling all the tutorials etc available seem to be more aimed at fully blown shows, whereas I believe my problem is much more simple. The images are contained in a directory and are numbered like so: img1.jpg, img2.jpg. img3.jpg and so on. the code I came up with so far is PHP Code: <script type="text/javascript" language="JavaScript"> start = '<img src="gallery/img'; end = '.jpg" width="150" height="200" />'; function getImage() { var n = Math.ceil(Math.random() * 10); // i have 10 images var FirstImg=(start+n+end); var n = Math.ceil(Math.random() * 10); var SecondImg=(start+n+1+end); } /* so now I think I have two variables: FirstImg = <img src="gallery/img1.jpg" width="150" height="200" /> SecondImg = <img src="gallery/img4.jpg" width="150" height="200" /> but i'm now unsure how i'd go about displaying this on the page. ideally the HTML generated would be: <div class="pics"> <p><FirstImg></p> <p><SecondImg></p> <a href="#" onClick="return getImage()">View More</a> </div> */ </script> Am I on the right lines here or am I way off?? Appreciate some pointers. thanks a lot. i'm trying to get this effect http://css-tricks.com/3458-perfect-f...kground-image/ except, instead of using an image, i would like to use a javascript image gallery. I was playing around with smoothgallery2.0 but I don't really care which I use as long as I'm just displaying images (no text) and there is a smooth fade effect (since the images are pretty high res). thanks so much in advance! Hi, I'm fairly new to javascript, I created a javascript image gallery using a tutorial found on web monkey. Please see below: Code: <script language="JavaScript" type="text/javascript">
<!--
var interval = 1500;
var random_display = 0;
var image_dir = "images/exhibition/"
var ImageNum = 0;
imageArray = new Array();
imageArray[ImageNum++] = new imageItem(image_dir + "exhibition-sealskinz.png");
imageArray[ImageNum++] = new imageItem(image_dir + "exhibition-orchard.png");
var number_of_image = imageArray.length;
function imageItem(image_location) {
this.image_item = new Image();
this.image_item.src = image_location;
}
function get_ImageItemLocation(imageObj) {
return(imageObj.image_item.src)
}
function randNum(x, y) {
var range = y - x + 1;
return Math.floor(Math.random() * range) + x;
}
function getNextImage() {
if (random_display) {
ImageNum = randNum(0, number_of_image-1);
}
else {
ImageNum = (ImageNum+1) % number_of_image;
}
var new_image = get_ImageItemLocation(imageArray[ImageNum]);
return(new_image);
}
function getPrevImage() {
ImageNum = (ImageNum-1) % number_of_image;
var new_image = get_ImageItemLocation(imageArray[ImageNum]);
return(new_image);
}
function prevImage(place) {
var new_image = getPrevImage();
document[place].src = new_image;
}
function rotateImage(place) {
var new_image = getNextImage();
document[place].src = new_image;
var recur_call = "rotateImage('"+place+"')";
timerID = setTimeout(recur_call, interval);
}
// -->
</script>
However unfortunately there are two issues, one is IE6 is coming up with javascript errors and IE7 gets an error when you click the previous button on the first image. The buttons look like this: Code: <div id="left-arrow-container"><a href="#" onClick="prevImage('rImage'); clearTimeout(timerID)"><img src="images/left-arrow.png" alt="left arrow" name="leftarrow" width="58" height="37" border="0" id="leftarrow" /></a></div>
<div id="see-the-whole-project"> see the whole project</div>
<div id="right-arrow-container"><a href="#" onClick="rotateImage('rImage'); clearTimeout(timerID)"><img src="images/right-arrow.png" alt="right arrow" name="rightarrow" width="58" height="36" border="0" id="rightarrow" /></a></div>
Being new to javascript I don't know how to get round these issues so if anyone could advise me I would really appreciate it. Thanks Gary Hi, I am new to javascript,this is my first time using it, I am wishing to have 2 buttons on my website, one that scrolls to the bottom of my page when clicked and then stops at the bottom and one that scrolls back up the page when clicked, but I want my viewers to be able to see this movement. I have some code (below) which works fine in firefox but it doesn't work in explorer, and I can't get this code to work moving upwards (after taking away the minus from -50). Can anybody please help me I have been battling for days trying to make it work although I am finding it hard to understand javascript being a first time user. I currently have this javascript : [CODE] <head> <script language="JavaScript"> function pageScrollup() { window.scrollBy(0,-50); // horizontal and vertical scroll increments if (window.pageYOffset) { scrolldelay = setTimeout('pageScrollup()',5); } } </script> </head> <body> <a href="JavaScriptageScrollup()">Back to Top</a> </body>[ICODE] Any help is greatly appreciated.
