I'm currently working on a photography web site, and so far I have a scrolling div with the thumbnails in:

http://www.amitypixels.com/zoom/gallerytest.php

The links at the top left (ScrollDown, ScrollUp etc) move the div content up and down respectively.

However my problem is that the client wants to be able to reorder the images in the div (currently they are listed in alphabetical order) similar to the way Facebook does it in their Ranking applications (if anyone is unaware of what I refer to, basically it's a list of your friends with UP and DOWN arrows so you can move them up or down the ranks by clicking on the arrows). Is there an easy way of doing this using Javascript? I don't really want to resort to Flash as this is only a budget job and Flash it kind of outside my knowledge.

Any help appreciated, thanks
Michael
