If not, is there a group of people somewhere who chase up copyvios like this?
I suppose the Free Software Foundation would be the body responsible for chasing up copyright violations, but, if they are anything like almost every other non-profit in the world, they probably don't have the time nor the resources to do so.
The individuals whose work is the object of the violation (i.e., the editor who uploaded the photo) could also chase up the copyvio by means of a private lawsuit, but obviously that isn't going to happen.
