Opps, I just clash a post with Nightmare...in the same instance.
Snowspeeder, in this case I think it is the model herself picking a picture of herself, so I wouldn't call it stealing.
Nightmare, I read the site, it may not work that way. It all depend on the agreement of prior to the shoot. There is an incident that a model discover her picture being used commercially in a Resort in Malaysia. She called the photographer and asked why she was not paid for her cut and only then both she and the photographer discovered their photos were used without permission. Subsequently the Resort agreed to pay in full and profits were shared by the model and the photographer. The Resort found the picture on the net but couldn't find the owners so they use the picture.
There is no fixed rule and many rules (or understanding) are verbal. I have done many model photoshoot and generally this kind of shoot the photographer is to use the picture for himself only. Any commercial use later the model can demand a share of the pay.
The final rule is what were agreed upon prior to the shoot . In KL, it is stated clearly pictures shot are to be used personally.
