I'm not worried. People can use whatever they want for whatever they want, especially for tossing around ideas like this. I just figured if you decided to use the image, before going through the work of removing the watermark (which is there for a reason), and you tried to follow waxers steps which will further degrade the quality of the image, I would put it out there to contact the original artist. I have dealt with Ron in the past, and he is a nice guy that was willing to give me rights to a couple of his stock images for next to nothing when I did some volunteer work for a small non-commercial project.
