Hi there,
The server you're linking to seems down, so I can't see what you mean exactly.
Have you ever heard of Lightbox?
http://www.huddletogether.com/projects/lightbox2/ It enables you to display images in a gallery-like fashion. Using it comes down to dumping a bunch of <a> elements in a page with a specific class. You can dump the images in the page using a ListView for example, and then let Lightbox take care of the rest.
If that's not what you want, please let me know when the link is back up, or post some more information.
Cheers,
Imar
