DHTML API allows you to animate your Web site with the aid of DHTML. Any content that you place within a div tag with the position CSS attribute set to absolute can be manipulated like a sprite. Just don't forget to set id="unique_name", and pass "unique_name" to the GetLayer() function.
AgileGallery is a photo gallery that processes the XML output from Picasa, generates paging and thumbnails, and displays the full sized photos along with any captions entered in Picasa. AgileGallery presently comes in two flavors: one that uses AJAX for the interface and one that uses Flash. AgileGallery does not require any server-side technology to generate photo galleries.
