One of the best ways I've heard of to "encourage" people not to directly
link is to:
1) change the image name for your site
2) change the linked image to a porno type photo. That tends to get
auctions shut
down fairly quickly :).
here or there... I had a huge spike in bandwidth
usage one time and
started to investigate, I had found nearly 4 dozen Atari related
auctions running on ebay at any given time using stolen images directly
linking from my server, so I cut off access to the ebay and subset
