Carbonize,
Thanks for the input. However, I'm not sure that I agree with your statement:
"If they like the design they would recreate it for themselves. Copying the image would serve no purpose."
I believe that copying the image gives them a much easier way of taking the image into Photoshop and manipulating it. Keep in mind that the designs (
http://www.eyemagination.us/starterdesigns.htm) I'm protecting are a single image and not already cut-up into html. This image could be easy reference material for duplication. Text sizing, bolding, special effects, location, ect. all play a part in easier duplication.
But, if I play devil's advocate for a bit, I also know that my design is one of millions of designs currently out there. And, if they really want it, they could get it (with some of the advice from the previous posts).
