How do I prevent image hotlinking

[darksaber76]

I know this is in the Hostrocket FAQ, but I am really confused. It's not been a problem for me so far, but I don't want to take any chances. On other webhosts the prevention of hotlinking was automatically there, so I don't know how to do it. It has something to do with .htaccess?? How do I prevent Hotlinking on my images without using a 'No right click' script? Anyone know that can explain it to someone who has limited coding knowledge? Maybe it can't been done with a free account on Hostrocket?? I don't know. Just wondering if anyone can help me.

Thanks

Heres a copy of my anti-leach code from my .htaccess file. I have it sitting in my images directory. This won't prevent users from "right-clicking" and saving images though - nothing can truly do that...
