[thelist] Using my graphics

[CDitty]

Hello all

I have someone using my graphics on a message board on another site.   I 
searched the net and found some code that is supposed to fix this.

RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://redhotsweeps.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.redhotsweeps.com/.*$ [NC]
RewriteRule .*\.(gif|GIF|jpg|JPG|zip|ZIP|png|PNG|swf|SWF)$ - [F]

However, it is not working correctly.  Does anyone see anything wrong?  I 
put this in a .htaccess file and put it in my images directory.
