7000 images? That is either stock photos or something adult, I presume. Maybe there is some idea in including a layer blend (or effect) that guarantees contrast whith whatever is underneath in the action. But you made me wonder about those adult sites (or stock bureaux like Getty)that have their stamp on every picture. I can not image they use interns to do that all day... Or people that thought something particularly glamourous was at stake when they read that would be handling photographs of beautifull women (or sunsets, for that matter) all day...
