A script to save bandwidth from thieves?

[Malice]

I have recently noticed a LOT of traffic hitting my site from unknown places. Upon further investigation I found out that people are using images from my site for avatars/blog pics/signatures etc etc. And they are ALL foreign language sites so I can't just ask them politely to save the images to thier own HDD instead of linking directly from my site. It is using up quite a bit of bandwidth according to my site statistics and I need to know if there is a script to stop it.

My husband said something about a "javascript referrer self" code, but I can't find any info on it and he won't tell me any more...says I need to figure it out or else I won't learn anything!

My apologies if this isnt in the correct forum, i'm not certain what category this would fall under. But any and all help would be most appreciated!

Thanks in advance,
~Malice

Perfect! I didnt know the term "hotlinking" so my searches for info were coming up with garbage. Thank you so much, this will be most helpful!
