RewriteRule .*\.(gif|GIF|jpg|JPG)$ http://site.com/bad.gif [R]

Because you fucked up. format c: and it will work... I think.

Try this, works for me.

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?site.com/.*$ [NC]
RewriteRule \.(gif|jpg)$ http://www.site.com/fuckoff.jpg [R,L]


Make sure you don't put your hotlink image in a directory that is protected, or it won't work.

The images you are using may be of big size and your server does not support them. Change the host.
