I don't have a clue, but couldn't you put all your images in a subdir and
get a .htaccess file in there and do a redirect for referrers other than
yourself?

Unless, of course, the client sends the referrer as part of the requests.
I caught this one time and ended up writing a (relatively simple) PHP
script to check for a key in a database that was inserted by the page that
referenced an image before it passed the image through to the browser.
This works rather well at locking out access to the image using that URL
after the first time it's used.

The only problem is the database table filling up with keys that never get
used (and subsequently deleted), but I have a Perl script running along
behind the PHP code to clean any old keys from the table.

Obviously, this requires access to the host to get all this working.
