CollagePlus
An image gallery plugin for jQuery

If you have an image gallery that needs an update in functionality, CollagePlus may be just the ticket. A jQuery plugin, it takes images and arranges them in a container that you define. It works even if you do not already know the sizes of all the images you want to display, making it easy to integrate images from sources that don’t specify image size for you. Six CSS3 transitions are included in the plugin, but of course you can code your own if you wish.
