Photographer who sold photos that weren't his

My apologies if this was previously posted as I haven't seen it here.

There's a story going 'round the internet about a photographer who steals other peoples' photos and sells them for enormous amounts of money ($90,000). Seems one of the victims is fighting back in an unusual way.

That's a funny way of fighting back. If everyone would be selling the same prints at ridiculously cheap prices he'd be out of business fast and he couldn't really start complaining about copyright or theft.
