There is a guy locally where I live who is a drug addict I think. He scans images from books he buys and passes them off as his own.I know because I turned him in to a manager here wqhere he was showing his stuff in town with the book he scanned the image from. I knew something was wrong becasue he was selling prints framed for 75.00, which is a lot to a heroin addict--he probably makes 45.00 on each sale. The frames are cheapos with plexiglass. I started looking and thuoght a few of his shots looked very familiar. Sure enough, I had one of the books, which was a Scott Kelby book from about 4 years ago, I think.
Tehre is also a guy here who does good technical photography, but that is his only talen really as he lacks in imagination and style. He had a show going and was advertising himself as a "wedding photographer" which I know he has never done. The picture he was using was from a magaxine, again something I noticed that I thought was very familiar. Sure enough, I had the book and looked up the image. I knew what he would say if I said something though, so I didn't. He would ahve said, "I didn't say that was my image. It was just something I used to show I do weddings."
There isn't much you can do about these skaggs really. Their just deperate people with no talent of their own and are out for the money, not the task of taking and doing good photograhy, and they know that marketing is the key, not good work. The problem is that they are correct. if you market yourself well, you can convince people you are doing good work when you're rreally doing snapshots. I now a person who does a specific type of photography, and the people getting it done ahve no idea it's not good. The person in question doens;t even know how to set aperture or shutter speeds, or ISO--or even what the do. They just bought a high end camera and push the button with a flash on the camera. No idea how anything works or how to change setting for a different look or effect.
It's not going to get any better. I think there is a "photographer" for every household now that anyone can pull teh trigger on a digital camera and print a 8 x 12 with their 100.00 printer that everyone in the family thinks is "talent."
On the other hand, I do think is someone takes your image and changes it at least 30%, it's not a copyright infringment. I put 72 DPI 700 pixel maximum wide images on my site with a transparent copyright in teh middle of each image. You can see what I mean here:

I'll never post anything larger or with more resolution and I never give away the RAW files or the high quality jpgs, unless someone is paying me big bucks so they can reprint when they want--and then they only get the jpgs, and never the RAWs. So if someone gets a minimum package done for 150.00 US, and they want the reprintable HQ jpgs, the price would go up to like 1000.00 US for a grand total of 1150.00.
