Re: [drewh01] How to randomize a upload display
Chris's method would be very stable, simple and fast (less server delay).
If you wanted the banners to rotate but on a timed increment instead of page refresh you could also incorporate some of the free code from dynamicdrive.com . I've done this for several clients to show thumbnails of product listings rotating every 2 seconds across the top of the page. I've also set up an "ad center" section inside CMSB for a client that allows them to change banner ads or banner code on the fly and appear automatically in certain pages and positions. CMSB makes this fairly easy and simple to do.
