The consequences of this ruling are fairly obvious: Porn company “Perfect 10 alleges that the display of the thumbnail is a direct violation of its copyright, and that the display of the larger image, even though it is hosted by a third-party Web site, constitutes a secondary copyright infringement on the part of Google. Judge Matz ruled that Perfect 10 had submitted enough evidence to conclude that it would succeed in a trial on its claim of direct copyright infringement.” If that’s true for porn, it’s true for any kind of photo, and that could open a big can of worms for the world of commercial and art photography.
