I've always wondered about stealing *cel* images. Since I have
worked and still do work with a lot of individually generated 
desktop wallpaper images, stealing without due-credit of a 
creative or semi-creative endeavor was obviously irritating 
(off-set with stamping and watermarking). I guess a mere 
photograph/scan sits less strictly with me. ..

Given my background, I do strongly back copyright issues and 
so forth, but I'm not the absolute purist either (it's impossible 
to be when considering the internet). If you don't want people 
to take your images, don't post them. Once they are up on the 
Web, they are free for the taking. If you like to share, but 
don't want people to off-link or copy withOUT credit due (i.e. 
saying it's theirs), then watermark and stamp your URL and e-
mail all over it. 

I assume that any graphic I put on my Web site will be copied 
somewhere by someone, sometime. So I watermark and stamp, it
works pretty well. I'm actually more worried about people 
stealing my bandwidth by directly linking to images. 

In fact, I'm building my cel gallery on the premise that 
people should be able to enjoy my luck as well (I never did 
like the brag-only galleries ^_~ unless they really do have 
reason to brag), so all my good-quality ANFS cels will be 
rendered in Photoshop as 800 desktop wallpaper for people 
to enjoy (with my watermark and URL stamped all over it, of 
course ^_^). This is going to be an experiment. ..
