I too quit posting my rare items because of the image ending up on ebay as a magnet, repo oil can or sign. I will try to watermark my pics also...
As for getting mad about writing a book and then someone using those picture??? I purchased the book and if I wanna print out a pic or use a pic out of it then I will. Its mine!
Total different story to steal images!
Too bad oldgas cant lock the images and keep people from downloading or saving the images to disc?
I keep my photobucket private so noone can steal them.
