Actually, they have no right to sell an image of someone who hasn't given permission. The subject of a photo must either share profit from the image or waive rights by giving them (or selling them) to the photographer. It's called a Model Release, and unless the photo was taken on public property, anyone identifiable in a picture must give permission for the photographer to profit from the image.
So the photographer can take a photograph, put it on her website, hang it in her gallery, sell prints made from the photograph, and even sell it to a newspaper for publication (journalism exemption) all without a model release. But, for instance, Comme Il Faut can't use the photograph to advertise without one.
