Script request

I'm running PunBB on a server and I have some images I want to randomise in my sig. No problem you might say. Thing is, they're hosted on photobucket and I really am too lazy to copy them all across. So could someone perhaps make a script that I could upload on my server to call a random image from my photobucket account? The URL for my account is http://www.photobucket.com/albums/d99/ReidE96/ and the version used for the images is http://i33.photobucket.com/albums/d99/ReidE96/ or at least that's what it gives me for static image linking.

My server supports PHP and Perl/CGI-BIN. Any help greatly appreciated.
