Photographer Mitch Aidelbaum has accused CNET of copying without permission a picture he took of Jerry Yang. One small problem with his claim: He actually did grant CNET permission, through a Creative Commons license. (He also asked CNET to hire him for later photo shoots.) While Aidelbaum later marked his photograph as "all rights reserved," the Creative Commons license, once granted, cannot be revoked. Still, fellow photographers are steamed at CNET for not attributing the photo on its second use — a possible violation of the license by which Aidelbaum granted CNET rights to use the photo.
