I couldn’t give a crap either way, but these two images are the main background images for both sites, and BOTH are featured on popular CSS Galleries. So, is this really “theft”? Where is the line between borrowed and “Hey, mother f’er!?”

Now, I’m not talking about Copyright laws here, which are pretty well defined…ethically, though, is this kind of thing wrong? Would you *really *get mad at somebody for grabbing your BG image?
