Second technique that spring to my mind is to have the server check
the "referrer" info on the request and hope that a) all legitimate
users are using browsers that include that info on image fetches and
b) that it's not worth anyone's trouble to hack up some sort of proxy
server to link through which would falsify the referrer info.
First technique that came to mind was to generate the pages on the
fly when requested and come up with a unique temporary name for each
image file -- good only for a minute or so -- for each page-load.
Eats up a chunk of CPU time on the server compared to static pages.
Neither of these will stop someone from _downloading_ an image, but
should prevent them from linking to it from offsite in an IMG tag.
