I know absolutely nothing about this kind of stuff, but someone on this board posted this a while back
RewriteEngine on

I use it briefly for stuff like alltheweb.com's image search crap. I wasn't sure what the implications for google would be so I removed it, but I seem to recall that it just blocked everything instead of trying to catch each domain that's hotlinking.
Any of you code gurus care to comment?
