When a photograph is posted on flickr.com under a license "Some rights reserved" and the photo also has the following instruction: "Request to license John or Jane Doe's photos via Getty Images" does that mean the person works for getty images or has getty images as an agent or something? What exactly is the working relationhip between Getty and a photographer who licenses their photographic contributions to flicker in this manner?
Don't know for sure. It could be Getty gets a percentage of any money collected.
Does that maybe mean, that if the person (John or Jane Doe) who could claim some rights on these fotos is unknown, that is, uses a fake-account or something like that, Getty Images gets automatically the rights?
I think Getty Images work as the agent or seller. Photographers can add photos to Gettyimages site in various sizes and others can buy from it. This way owner of the photos have let work to be done.
