How do we protect our copyrighted work? Should professional photographers watermark every image? This image was taken from the actual client's site, it was not swiped from mine. So a watermark would not have worked in this case anyway.
And more importantly, how do we educate people? This person clearly thought it was acceptable to swipe an image and use it for her business without permission. To be honest, I probably would have let her use my image for free if she had simply asked first.
