In an effort to get people to actually visit our department site, I'd
like to be able to have random images from the photo library display
on the homepage.

I've found the This Week in Pictures option, but would really prefer
something that refreshes with each browser load.

I've searched online and have found vendor web parts, but of course,
have no budget to justify something like this. Does anyone know how
to do this? I've heard others have managed to do it as well without
having the enterprise edition (we dont) so there's got to be something
I'm missing.
