just had a bunch of people stealing bandwidth by using graemlins from our server. this is basic, but worth posting:
how to block stealing of .gif and .jpg using .htaccess:
<br />RewriteEngine on <br />RewriteCond %{HTTP_REFERER} !^$ <br />RewriteCond %{HTTP_REFERER} !^http://(www\.)?yoursite.com/.*$ [NC] <br />RewriteRule \.(gif|jpg)$ - [F] <br />if you place this in the root of your public http directory it will protect all images on your site.
