JavaScript - Proportionally Fitting Images In Slideshow 2!

Hi, i have a slideshow that works.
I want to store my images in a folder images/slideshow/1.jpg for all my images up to 10.jpg.

I have tried to adjust the code so i can store the images in a folder but the code cant find the images.

Any help would be greatly appreciated, thank you.


I have this code in the head section:

<script type="text/javascript">
thisImg=1;
imgCt=10;
function newSlide(direction) {
thisImg = thisImg + direction;
if(thisImg <1) {thisImg = imgCt;}
if(thisImg > imgCt) {thisImg = 1;}
document.getElementById('slideshow').src=thisImg + '.jpg';
}
</script>




I have this code in the body section:

<form>
<img src="1.jpg" id="slideshow" alt="Photo slideshow" width="213" height="184" >
<p>
<input type="button" value="<-- Previous photo"
onClick="newSlide(-1)">
<input type="button" value="Next photo -->"
onClick="newSlide(1)" >
</p>
</form>

Hi people, I am using a drupal module, views slideshow, it displays images on my site, the landscape sized images are showing fine, however the portrait images are not centered but aligned left and they look cramped over to one side, I have tried css and its not working for sure, this is the script, Im sorry but I no absolutely no javascript so if anyone can figure this one out I will owe you one. I guess it will need to check for the largest width in the slideshow and then half this for the centre. the link to the file is here aswell http://www.2shared.com/document/3kyc...slideshow.html

PLEASE! I NEED HELP!
I inherited this problem from a client who insists on keeping this template. I've got all of the images in the correct folder, the slideshow css is correct, but I'm not sure how to edit the Slideshow.js file to show the 2 additional images. The first 3 images work perfectly. I was able to swap custom images for the original images without a problem.
Here is the Slideshow.js code

Code:

 var $$ = $.fn;

$$.extend({
  SplitID : function()
  {
    return this.attr('id').split('-').pop();
  },

  Slideshow : {
    Ready : function()
    {
      $('div.tmpSlideshowControl')
        .hover(
          function() {
            $(this).addClass('tmpSlideshowControlOn');
          },
          function() {
            $(this).removeClass('tmpSlideshowControlOn');
          }
        )
        .click(
          function() {
            $$.Slideshow.Interrupted = true;

            $('div.tmpSlide').hide();
            $('div.tmpSlideshowControl').removeClass('tmpSlideshowControlActive');

            $('div#tmpSlide-' + $(this).SplitID()).show()
            $(this).addClass('tmpSlideshowControlActive');
          }
        );

      this.Counter = 1;
      this.Interrupted = false;

      this.Transition();
    },

    Transition : function()
    {
      if (this.Interrupted) {
        return;
      }

      this.Last = this.Counter - 1;

      if (this.Last < 1) {
        this.Last = 3;
      }

      $('div#tmpSlide-' + this.Last).fadeOut(
        'slow',
        function() {
          $('div#tmpSlideshowControl-' + $$.Slideshow.Last).removeClass('tmpSlideshowControlActive');
          $('div#tmpSlideshowControl-' + $$.Slideshow.Counter).addClass('tmpSlideshowControlActive');
          $('div#tmpSlide-' + $$.Slideshow.Counter).fadeIn('slow');

          $$.Slideshow.Counter++;

          if ($$.Slideshow.Counter > 3) {
            $$.Slideshow.Counter = 1;
          }

          setTimeout('$$.Slideshow.Transition();', 4000);
        }
      );
    }
  }
});

$(document).ready(
  function() {
    $$.Slideshow.Ready();
  }
);

The html code for the pages looks like this:
Code:

Alrighty so here's what I have.
Live example:
http://www.thestrikeforum.com/ex/

It's a image slideshow that dynamically gets all the images (via php) in the current directory and puts them into the slideshow array. The array then randomly displays the images in the slideshow (via javascript).

There are 5 images in the folder rotateimage which also has the php script getimages.php in it.

Currently only the first image fades in however I want all the images to fade in as the first one does.

Codes:

Php script that gets all the images for the array:
PHP Code:
<?

//PHP SCRIPT: getimages.php

Header("content-type: application/x-javascript");



//This function gets the file names of all images in the current directory

//and ouputs them as a JavaScript array

function returnimages($dirname=".") {

$pattern="(\.jpg$)|(\.png$)|(\.jpeg$)|(\.gif$)"; //valid image extensions

$files = array();

$curimage=0;

if($handle = opendir($dirname)) {

while(false !== ($file = readdir($handle))){

if(eregi($pattern, $file)){ //if this file is a valid image

//Output it as a JavaScript array element

echo 'galleryarray['.$curimage.']="'.$file .'";';

$curimage++;

}

}



closedir($handle);

}

return($files);

}



echo 'var galleryarray=new Array();'; //Define array in JavaScript

returnimages() //Output the array elements containing the image file names

?>

Hi, thanks for your time first of all-

secondly, I am at a loss for what to do next to get these slideshows functioning. You can see the current iteration he http://www.pauljameswilliams.com/portfolio.html

I am using hte plug in galleria, and I have got it working in a stand alone version with the same images and and folder structure. The difference may be that I have the content nested in these div tags? to create tabs. i really don't know.

Here is the structure within the portfolio tab, under the Identity heading: ( there will be more images once I get this working:

Code:

<div>
<div class="demo">
<ul class="gallery_demo galleria">
<li><img src="images/portfolio01.jpg" alt="Flowing Rock" title="Flowing Rock Caption"></li>
<li><img src="images/portfolio02.jpg" alt="Stones" title="Stones - from Aple images"></li>
<li><img src="images/portfolio03.jpg" alt="Grass Blades" title="Apple nature desktop images"></li>
</ul>
<div class="galleria_container"></div>
<p class="nav"><a href="#" onclick="$.galleria.prev(); return false;">previous</a> | <a href="#" onclick="$.galleria.next(); return false;">next</a></p>
</div>
</div>

I can give you more code if necesary, but I don't want to overwhelm anyone. thanks.

Ok, I am in a small pickle here.

I created a sidebar gadget for work originally with only 4 images that needed to cycle though it. Easy enough script done.

Now they have 6 images that need to rotate through.
Easy enough again, script done.

The issue I have is now I have to re-push this updated html file to all 1000 PC's on my network. Plus every time a change is made I will have to do it again. And we change the images multiple times a month.

So what I need help doing if its possible is to modify the html file i am listing below to have a second IF parameter that not only steps the image but also checks to see if the file is even there.
This is the spot I need help at.
Code:

function slideit(){
			if (!document.images)
			return
			document.images.slide.src=eval("image"+step+".src")
			whichimage=step
			if (step<10)
			step++
			else
			step=1

I wanted to add another part to the IF statement like maybe.
Code:

If (step<10 && file_exists("http://www.akronlibrary.org/Gadget/Gadget Pic 1.bmp"))

Basically a step that checks to see if I have at that moment a file named gadet pic 1. (I would do or statements for all of the file names)


The point is to make this whole thing dynamic, so that I change image 1 on the server and every gadget on every PC looking for image 1 now see the new image. This way I just change the image file name when I want a different image to display. Same thing with the var for the slidelink function. points to a static named html file on my web server and I just change the redirect in the static named html file to go where i want it.

I am by NO means a programmer, I am actually a network admin that came up with this idea and I am trying to fumble through it. Thanks in advance!

Hey guys I'm need to put a photo slideshow on my website with a lot of images. I don't want all the images to download as you come to the website as this would take forever. Are there any pretty simple slideshows that load images just before they are about to come in the view?

How will the program know which image is "about" to come into view? Or are they viewed sequentially? If so there is no need for preloading images to take "forever". Preload the first (say) 5 and then preload the rest while the user is viewing the first ones. Or when each "next" image is selected for viewing preload the next following one.

Hello. I was wondering where I can find something like this:



It's a slideshow. I need one for my site. Thank you.

I worked a lot with a friend to change the code, and it's almost there. The next and last buttons still work. The Start buttons is titled 'wri' and the latest button is titled 'end'. The end button does not work. Before I added the end button, the start button worked, but now it sends you to the image alt. Any ideas on what went wrong?

Code:

window.onload = initLinks;

var myPix = new Array("comic/Issue1_Page00.gif","comic/Issue1_Page01.gif","comic/Issue1_Page02.gif");
var thisPic = 0;

function initLinks() {
	document.getElementById("prevLink").onclick = processPrevious;
	document.getElementById("nextLink").onclick = processNext;

}



function processPrevious() {
	if (thisPic == 0) {
		thisPic = myPix.length;
	}
	thisPic--;
	document.getElementById("myPicture").src = myPix[thisPic];
	return false;
}

function processNext() {
	thisPic++;
	if (thisPic == myPix.length) {
		thisPic = 0;
	}
	document.getElementById("myPicture").src = myPix[thisPic];
	return false;
}

// Load Images
if (document.images) {  

  writeImg = new Image();      
  writeImg.src = (comic/Issue1_Page03.gif);
  
}

function imgOn(imgName) {
  if (imgName == 'end') { document.strip.src=eval("writeImg.src"); document.txtwriteImg.src=eval("txtwriteOnImg.src"); return true;}

  return false;
}


// Load Images
if (document.images) {  

  writeImg = new Image();      
  writeImg.src = (comic/Issue1_Page00.gif);
  
}

function imgOn(imgName) {
  if (imgName == 'wri') { document.strip.src=eval("writeImg.src"); document.txtwriteImg.src=eval("txtwriteOnImg.src"); return true;}

  return false;
}

Hi,

I desperately need a javascript slideshow that does the following:

1--shows still images with thumbnails
2--can be played manually or automatically
3--can embed youtube videos
4--audio can accompany slideshows
5--powered by javascript, not Flash so it shows up on iPad

Does anyone know where I can get such a slideshow? Thanks

Hello everybody!

first of all I must specify that I don't know almost anything about javascript... I'm trying to introduce a javascript slideshow (I found a free one) on our website and I have a problem:

As you can see here on the bottom of the page (http://www.comelity.com/en/pages/about-us.php), when the slideshow changes image, it puts a link over the image without any reason and if you click on the image it reloads the page... I would like to remove this link, but I'm not able... Does anyone know how to solve the problem? I can send the javascript slideshow if you want...

Thank you very much!

S.P.

Code:

var mySlideShow = document.getElementById("slideShow");

var imageArray=new Array(); 
imageArray[0]="url(images/Slide1.JPG)";       
imageArray[1]="url(images/Slide2.JPG)";
imageArray[2]="url(images/Slide3.JPG)";


var imageIndex = 0;

var leftArrow = document.getElementById("left");
var rightArrow = document.getElementById("right");

mySlideShow.style.backgroundImage = "url(images/Slide1.JPG";


function changeRight  () {

mySlideShow.style.backgroundImage = imageArray[imageIndex];
imageIndex++;


	if (imageIndex >= imageArray.length) {
	imageIndex = 1;


	
	}
	
	console.log(imageIndex);
	
}


function changeLeft  () {

mySlideShow.style.backgroundImage = imageArray[imageIndex];
imageIndex--;
console.log(imageIndex);
	
}




rightArrow.onclick = function() {
	
	changeRight();
	
	}
	
leftArrow.onclick = function() {
	
	changeLeft();
	
}

So what I am trying to do here is basically a slideshow. When I click on the left button it goes backwards and when I click the right button it goes forward. The problem arises when I click on the left arrow. It doesn't act as I want it to and I need some help. I want to remove one from the image index but imageindex--; doesn't seem to work.

Any help would be awesome.

This slideshow has a drop down menu that lets you go from one picture to another.

Can someone help me modify it so that instead of a dropdown menu i have a list of numbers (horizontally,not vertically)?

I know absolutley nothing about javascript. sorry.

Thanks programmers!

I am having a problem with my homework assignment and can not figure out the problem. Debug comes back clean and I am stumped on this project for several hours. I hate asking for help and like to figure it out on my own, but I can not seem to know what the problem is. I have done alerts in my blocks of code and everything is coming back.

Here is the book and the case problem I am on:
http://books.google.com/books?id=BeE...page&q&f=false

Basically the images is not loading up, or anything is happening.

//EDIT : I have the function setup() onLoad in the body ( body onload="setup()" )

Here is my code:

Code:

function getStyle(object, styleName) {
   if (window.getComputedStyle) {
      return document.defaultView.getComputedStyle(object, null).getPropertyValue(styleName);
   } else if (object.currentStyle) {
      return object.currentStyle[styleName]
   }
}

// step 3
function addEvent(object, evName, fnName, cap) {
   if (object.attachEvent)
       object.attachEvent("on" + evName, fnName);
   else if (object.addEventListener)
            object.addEventListener(evName, fnName, cap);
}
//step 4
