RewriteEngine On
RewriteCond %{HTTP_REFERER} !^$ [NC]
RewriteCond %{HTTP_REFERER} !^http://([a-z0-9-]+\.)* [NC]
RewriteRule .*\.(gif|jpg|jpeg|bmp|png)$ - [F,NC]

The above is something you can stick into your Apache configuration to
do that. It'll affect all gif/jpg/jpeg/bmp/png files. You just have to
replace "" with your domain name.
