Last year, I took way too many youth baseball pictures and did not really sell much, so I gave it up. I still go shoot my friends' kids and today there was a new guy out on the field shooting away. I checked out his website and he is selling the digital downloads for commercial use. I know for a fact that my friends have not signed any kind of release for him to make their images available for commercial use. Can he sell these images for commercial use without a release from the parents?
