so, Dirty White Boy, my solution would still be the same. Don't post pictures and people cannot copy them. Or post them in so bad of a quality setting that no one will want them.
And, I believe your comparison to what that student told you about purchasing a CD, or a music download, falls a little short. The artist has been paid at least something by an individual. In most instances, a photographer has not been paid a dime for an image downloaded.
What really ticks me is people think there's nothing wrong with it. Or, what happens when someone pulls into a gas station and pulls away with a free downloaded tank of gas? Imagine going to a movie theater, making a copy of it and then giving it to a friend. Or buying a ticket to a movie, using it and then turning and giving to a friend so they can use it also.
Downloading a picture is just as wrong and the courts will ultimately uphold that position.
