Don, do you want to work on this? If you do, I can point you in the right
direction, as far as scripts to alter and such.
It's been my plan to use ldglite offscreen for this. But we should cache
the images after they're generated, since CPU time on the server is at
something of a premium.
I can think of two cached-image approaches:
1. Always generate a new image file when a file is submitted. This can be
handled by the back-room posting script.
2. Have ptdetail.cgi check for an existing image file, and only generate it
if needed (either ptdetail.cgi compares the mod date of the .dat and the
image, or the back-room process erases old image files).
The main advantage to #2 is that it won't spend any time generating unused
images.
The main advantages to #1 are: it's simpler, and cgi's are more restrictive
security-wise -- it would be slightly harder to manage shelling out to
ldglite, and writing the image files to disk.

| (...) Perhaps the offscreen rendering version of ldglite could be used at ldraw.org to generate these pics on the fly in a CGI script? Don (23 years ago, 15-May-02, to lugnet.cad)
