Anti-Hotlinker Mod Rewrite Script
If you have apache mod-rewrite installed on your server you can use this script to stop people from hot-linking your images. Consult your sys admin if you're not sure if you have mod rewrite or not.
Put this script inside your .htaccess file. It will protect everything in this directory and below.
The yourdomain and yourdomain.com should be replaced with any domains and ip addresses that are allowed access. You should always include the ip address of your domain into this script.
