Random Image Rotator

Hmnm, I think this is the right board to post this on. If this is not, my apologies, and Id appreciate it if a mod would move it to the right board, and let me know for future reference. =]

Im looking for a Random Image Rotator script. No, I dont want a slide show. One image for every reload. Not a group of rotating images for every reload, just so we are clear. I have already done a few searches for one, and I found this but, I was having troubles and it did not end up working for unknown reasons. So if any of you know of any others I would greatly appreciate it. Thanks. =D
