There's nothing you guys can do. When some jerk was selling my pictures on eBay and making money off of them, or my scans, I couldn't get eBay to stop them and they legally should have. This is just typical internet theft. Considering it's just some dinky website, don't even worry about it. Get angry if people take your colorized photos and make a profit from them.
This person is obviously an idiot, because the black and white images are all public property regarding copyright. However, the colorized photos are modified public property and therefore the colorizer's (I made up a word!) creative property. Again, there's nothing you can do about it if she's not selling them. Obviously she just took them from the website here; she's certainly not clever enough to get rid of the website title on the images, at least. Moron.
