I recently discovered that I've had a few images re-pinned from Photo.net onto peoples Pin collections. I have mixed emotions about this. As an amateur, I find it flattering. On the other hand, I think that it can be a bit dubious. In my case, the linked images take you straight back to my Photo.net gallery, so I don't see this as a copyright infringement. Do you agree?
While I do not charge for my nature, wildlife and macro images, the cost of equipment, learning materials, software, electronics, not to mention the countless hours shooting... certainly adds monetary value to my work. Whether its deserved or not is a question for another day.
