So Getty is in possession of a stolen celeb nude selfie and applying their own copyright to the image?
Sounds like typical of Getty.
I have no idea what kind of nude pictures Getty may have in its inventory. . . but any use of any Getty image without permission will unleash them and their demands for unreasonable licensing fees. . . in perpetuity. They will demand thousands of dollars for using one of their images, even one without a copyright notice, or inadvertently, and will they will be like a pit bull with a bone, demanding payment, threatening lawsuits, and other dire consequences unless and until you pay up. Eventually, they will unleash their attorneys on you for another round of demands with even higher dollar values for the use of their image or portion of an image.
