Lisa, there's a series on TLC about that subject.
Notice they don't even credit the photographer for the photo, only Thinkstock.
For all you Getty haters, the CNN site is full of images like this marked Getty Images, no credit to a photographer. Some pages have image courtesy / "someones name", some are Thinkstock no credit but the photos came from the wholly owned collections of Getty, not us. Contract deal with CNN no doubt. Another way to look at it. No one is missing a sale because there aren't any from other sources, except in an exclusive case where Getty or ThinkStock can't provide them.
I still say, everyone can remove all their images from IS partners and it's not going to change things one bit. We are not the value or important to the site. People need to understand that ThinkStock is nothing but a collection of old (stale?) collections that Getty markets as cheap subs.
Getting all upset and ranting about ThinkStock is a waste of energy. It's not a micro site, it's not fresh or new, it's just old stock shots, cheap. It's not going away either!
