A template project, using HTML5 Boilerplate, has been included with the default values.
This is JSGif. With it, you can use Javascript to loop through a sequence of images (up to 1000 total) just like a gif, without the color compression.
All one needs to do is somewhere in their HTML have an image attribute with an ID, optionally have a checkbox attribute with an ID that determines whether or not to reverse the loop at the end, include these lines:
<script src="js/imageLooper.js"></script>
<script type = "text/javascript">
window.numberOfImages = 100;
window.folder = 'loopImages/'
window.imagePrefix = 'image_'
window.fileExtension = 'png';
window.imageId = 'currentFrame';
window.reverseBoxId = 'reverseCheckBox';
var pictureArray = imageStringArray();
//if you don't want to use buttons to start the loop, make sure you call the startLoop() function somewhere.
//startLoop();
</script>
And change the variables based on your data. These values are all the defaults.
For example, I have a sequence with 217 images, each named dog_###.jpg, in the folder pancakes/, and I want the images looped in an image with the id snails.
I would write this:
<script src="js/imageLooper.js"></script>
<script type = "text/javascript">
window.numberOfImages = 217;
window.folder = 'pancakes/'
window.imagePrefix = 'dog_'
window.fileExtension = 'jpg';
window.imageId = 'snails';
window.reverseBoxId = 'reverseCheckBox';
var pictureArray = imageStringArray();
//if you don't want to use buttons to start the loop, make sure you call the startLoop() function somewhere.
//startLoop();
</script>
If you want to start the loop, call startLoop(), if you want to stop, call stopLoop().
