There's a notorious case in Germany wherein Getty actually sued somebody.
It appears that the alleged infringer arranged some sort of retroactive deal with the artist, and Getty lost in court.
"In Germany, Getty images lost a court case to an individual after the person has proved that he gotten exclusive rights from the photographer."
http://en.wikipedia.org/wiki/Getty_imagesBut, at first I heard that the alleged infringer already had a license, later I heard that he got a license retroactively.
So, it's a bit unclear what the story is.
A few people on this forum have contacted the photographer/artist in their cases.
One didn't respond, however, a couple replied with details about their copyright status in regards to the images.
I don't think that any retroactive deals were made.
Does anyone else have further info, or experience?
