Download stock photos without paying, don't go to jail. Istockphotos.com seems to be offering free stock photography submitted by artists and photographers. And it's endorsed by Zeldman, even. But... what's to keep people from uploading Eyewire images and calling them their own, thereby illegally distributing them to thousands of people who'll use them on websites, magazines, etc. Istockphotos is legally covered, but what about the designer?
