Hi Currently my website waits till all images are loaded up first: Code:
$(document).ready(function(){
* LOAD UP ALL THEM IMAGES FIRST... *
$(window).load(function() {
letsLoad();
fadingEffects();
});
However my website now has over 200 images on the website and now its taking way too long to load the images. My question's a 1. Is it possible to either load the site when its around 20% or even 50% loaded? OR 2. If its possible to give certain images a tag?? and when these images are loaded then the site loads? Heres a link to the site - must warn you need broadband and a high speed connection takes way to long to load. Takes me around 1minute 30seconds http://www.arcvizio.co.uk/ovoma/2/index.html Thanks Hi, well i searched at google and was not exactly able to find what i was looking for, i am looking for a script the shows by logo while loading the game at back end, shows loading percentage or bar representing how game is loaded and then makes the my logo disappear once the game is loaded e-g like this site has used http://www.gamegape.com/en-2095-elemental-battles.html if some thing like this is not available can someone atleast tell me how this site has done it, so we could copy it from them ^_^ Here's what I usually use and have been using for years and it works great, just not for this particular purpose. I don't have a clue when it comes to javascript. Code: <noscript><img src="no_script_quote.gif" width="406" height="94"/></noscript><script language="javascript">
var delay=6000
var curindex=0
var images=new Array()
images[0]="quote1.gif"
images[1]="quote2.gif"
images[2]="quote3.gif"
images[3]="quote4.gif"
images[4]="quote5.gif"
var preload=new Array()
for (n=0;n<images.length;n++)
{
preload[n]=new Image()
preload[n].src=images[n]
}
document.write('<img name="defaultimage" src="'+images[Math.floor(Math.random()*(images.length))]+'">')
function rotateimage()
{
if (curindex==(tempindex=Math.floor(Math.random()*(images.length)))){
curindex=curindex==0? 1 : curindex-1
}
else
curindex=tempindex
document.images.defaultimage.src=images[curindex]
}
setInterval("rotateimage()",delay)
</script>
But, now I want to be able to set a default picture to be shown first and have the random pics appear next. I also don't want the default pic to show up again in the random array. So basically, every time the page was first visited, or refreshed it would show the default picture then move into the random pics. Is there anyway to modify the code that I'm using to accomplish this? Or... Any help would be appreciated. Thanks, Dell I am working on a demo for a movie site, and 90% of everything seems cool. Here I am doing php.flushes, .htaccess caching and using PNGs to help with performance. I might start using another sub site to grab all the scripting from to increase performance, but it seems a tad bit slow at the moment. - There are a few issues one being when you click on X-Men and look at the gallery the images seem to flicker sometimes going from image to image. I am using a fade script I found and then using setTimeout() to give the fade script time to do its thing then call for a new image. Code: FadeOpacity(main_img_id, 100, 0, 600, 12);
setTimeout("updateGallery('"+target_arr+"','"+main_img_id+"')", 600);
- Also in the same area I am checking clientHeight after each image modifying the marginTop. The thing with that is the clientHeight only seems to update after the second function call. I tried using a setTimeout() but that didn't nothing. Code: document.getElementById(main_img_id).src = "assets/movie_images/"+arr[i]; img_height = document.getElementById(main_img_id).clientHeight; Any suggestions with improving image load performance, the clientHeight issue or the image flickering issue would be appreciated. Hi Chaps, I'm looking for a 'preloader' progress bar to appear whilst a file is uploaded/downloaded from my php app. Not sure whether this is a Java/Flash question, but any help would be appreciated. Cheers Hi everyone, I was wondering if anyone could help me figure out how to overlay a javascript game with buttons and such onto a background image? Let me know if that's too vague a description.
Basically, I have a Simon Says game with very simple functions but I added an image map with buttons that I now want to use, rather than a table with images as buttons. The problem is, now I can't get the game to work with the image map. Can anyone help me?
hi everyone. i have to create the 15 puzzle game and im having a difficult time getting started. can anyone help? i need to create a table (4x4) that has one empty space. All the other spaces must have a random generated value between 1 and 15. All i got so far is a onclick image swapping function.... need help! thanks
I have multiple images and am trying to load it as an array. It's the first time I've used this method and I don't think it's actually working. Here's my code: Code: <script type="text/javascript">
<!--
if (document.images) {
var slides = new Image();
var pic = new Array();
pic[0] = "images/cottage/livingroom.jpg";
pic[1] = "images/cottage/bed.jpg";
pic[2] = "images/cottage/kitchen.jpg";
pic[3] = "images/cottage/porch.jpg";
}
//-->
</script>
What do I need to make sure it works? Hey guys I've a download page with a button 'DOWNLOAD NOW'. When the button is clicked visitors will have to wait for the download to starts (doesn't redirect). What I want is that sometimes it takes very long for the DL to start after clicking the button, for instance 10 seconds. Hence I want to show a simple preloader WHEN the button is click, while waiting for the browser to stop loading and download to start, AND hide the preloader when browser stop loading and download started. I've created a javascript version of the classic game SOKOBAN. Basically what happens is you move the man around the "warehouse" and he must push the boxes into the target area. Copy the code and try it yourself to see what I have so far (note-he can't move the boxes yet). My question is: Right now, my map consists of solid color blocks. What I WANT them to be is image files (for example: box.png, wall.png, floor.png) to add a little versatility and life to the map. I am not sure how to make this switch though. I suspect I make the change somewhere in the tile array in the initialize function, but I am not sure what.. Also, how can I get the boxes to actually MOVE? I.e. when my man pushes them, they move around in the direction he pushes? Any help would be much appreciated.

Hi I have a script which dynamically adds contents to an HTML table using the jQuery's .after();... Now the problem the content is a bit too much and some times IE would crash, so I thought if a loading image would solve this issue? Any ideas? Thanks in advance My goal is to replace a 300px x 300px div with a random assortment of pictures, all being 300px x 300px. I however am not that great at JavaScript (I've taken a bigger bite than I can chew) and would love your guys' help. So far this is what I have for my JavaScript: Code: begin();
function begin()
{
setTimeout(newimage(),7000);
}
function newimage()
{
}
Which brings me to my first question: What's the best method of pre-loading images? And also, if the method is not through JavaScript, how would I reference the image from the JavaScript? My next step would be to transition between images. (Fading specifically.) I really like the fade transition here and I plan on using that in the site. How would I incorporate that into my code? I noticed he made the entire JavaScript code into one line, which is quite annoying. Thanks guys! So I'm creating a game and decided to use a canvas for the map. The map is a big pictures 500kb+ (6400x6400px) and the canvas size is 320x320 so I am displaying only part of the image at a time and have the page reload on button click for database purposes. What I'd like help with is performance. Currently it's taking a few secs to reload every time and it seems that it causes some cpu strain (can't switch tabs while loading). Could I stop the canvas from reloading the image each time the page is reloaded and if so then how? Can I make the canvas only load a part of the image, if so then how? If neither is possible any tips, solutions how to solve the performance issues? Hi, I want to load an image when a user clicks a link on my page. The image is a tracking pixel for an affiliate network, so it doesn't need to be visible to the user (as it's not an image anyway but a php file). I assume this would use the onclick event. Can anyone help? Hi! i am working on a facebook like photo viewer. I have used javascript to declare an array of about 200 images. I have the following approach to pre-load the images. I preload all the images when the page loads: HTML: <body onload = "lodpic()"> JAVASCRIPT: function lodpic() { for(i=0; i<=199; i++) { LODImage = new Image(); LODImage.src = picture[i]; } } The problem is the page tries to load all the images when opened. And when the user clicks "next" to view other photos, the other photo is still loading where as some are already loaded. I would like the code to be able to load the photo that the user is currently viewing as the user gets to that picture, before the page tries to finish loading all the photos. In other words, if the user wants to view a particular photo directly, that photo should get the priority of loading quickly. Or if there are other approaches, it would be really helpful. Thank you! ok. so i have all these big images and i need to let the whole page load before the viewer sees it what i would like is for a separate url (or something to completely cover the html page so you cant see it loading) to say please wait or something like that. Help! I have a form that used php to load a random image but now i would like to use javascript instead and am sure I nearly have it. I need to have a random number between 0 -5. Here is my code Code: <script type='text/javascript'>
var random = Math.floor( Math.rand() * 6);
document.write("<img src='images/'"+random+"'.jpg' alt='random image' /><input name='image' type='hidden' value='"+random+"' />")
</script>
