Sorry, I don't know where to get any 12-bit JNG images
(image-sample-depth 12 or 20).

Compile libjpeg that way and make your own (12-bps JPEG/JFIF, that is),
then slap some JNG headers on it and you're set.

Possibly there are already some JPEG/TIFFs out there that could be
adapted, too, but TIFF is kind of a mess to pick apart.
