That's right: she was not only unhappy with her photographer, but she then stole her photographer's image and used it to market her sudden, new-found photography skills!
1. Unless there is a different agreement, in writing, any and all images taken by the photographer are the sole copyright holder of that image. All rights belong to the photographer, even if you are in the image.
2. A model release says the person being photographed has given consent to be photographed and to the use of the images you capture. It doesn’t apply to professional models or situations where people know they are posing for photos.
3. A property release says that the owner of a certain property, such as a pet or a building, has given you consent to take and use images of the property. You don’t need one for public property, such as government buildings.
4. Taking an image without permission or credit, for any use, is illegal. Even if you are only creating a meme, it is intellectual theft.
The contracts and releases you obtain should be saved and should be linked in some way with the photographs to which they relate. You can expect to be asked to produce them whenever you license an image, and you may need them if you find yourself in court.
