OK, this evening I just wrote a little CGI script to do this for images in
the sets-DB. So, the dynamically generated HTML pages, i.e.
http://www.lugnet.com/pause/search/?query=8880-1
now link to this CGI script -- which acts as a buffer -- rather than to the
raw JPEG image file. Thus, the URLs it now uses look like:
http://www.lugnet.com/img.cgi?pause/technic/tech8880.jpg
instead of:
http://www.lugnet.com/pause/pix/technic/tech8880.jpg

For backward compatibility (for a very short time -- maybe a few days or a
week or two), the old image directory will stay in place at its current
location -- so that the old direct-image links will continue to work (for
now). This gives a transition period while auctions close and old links
fade out, while still making it very difficult for anyone to add any new
unauthorized image links.
I'll leave the old directory at its current location for as long as I can
stand it -- then I'll rename it, moving it to a location outside of the web
server's area of access but still inside of the the CGI script's area of
access. This will then finally break any remaining unauthorized links.
Whew. :-p
