Check out Rainbow Passport. They have some pretty sticky rules about no external links on your gallery, but they are completely gay and their premium product isn't bad. I don't make a fortune with them, but I do alright. And I've had some pretty consistent and substantial rebills. I just haven't had the time to completely market these guys properly.

Hint: if you use RP you'll have to create one clean page you submit to them and another page that has your link list banners. Otherwise, they'll drop you out of their search engine. However, to be honest, I never got a ton of traffic fromt heir own search engine, so it may not be worth the bother. They'll still pay you the same and pay you rebills if you're not in their search engine, they just won't sent you any traffic if you have external links.
