Yes, I use a CGI PERL script to prevent bandwidth
stealing for the proggies on my site and right
now just one pic.. I'll probably move most of my
site behind the script later. ^_^

I forgot another option to make image stealing 
more difficult is slicing. 

I also know a way to prevent image stealing 
*altogether*, but it's a method I'd personally 
never use since it requires a Java wrapper, and I 
just don't like client-side Java... Too slow. -_-'
