Copyright and My Photos

I have seen print-outs of my photos passed around and many people tell me they use my photos for wallpaper or as background screens on their computers. That doesn't bother me so much but when someone tells me their daughter downloaded some of my photos, printed them out, framed them and given them to him as a present that really pissed me off. I work very hard to get my photos and am not in the habit of giving them away for free. I earn very little money as it is (choosing to teach 1/2 time so I have my mornings free for photography) so it riles me that people take my photos off the Web site and print them out and give them as gifts when they should be paying for them.

Today I added some code to my site that disables right clicking. I know it's easy to get around this but I am hoping it will make people stop and think before the take one of my images off the site. I also added additional information at the bottom of every screen--a warning and info about how to purchase a print. I have also registered every image on the site with the U.S. Copyright Office so that I may seek punitive damages against particularly egregious offenders.
