The XP box, where everything goes fine, has gd-2.0.33 whereas this troublesome Vista box has gd-2.0.35. Other than that, it's the same set up - GD-2.46 and jpeg-6b.

Later on today I'll upgrade the XP box to gd-2.0.35, and expect to see the same error as occurs on the Vista box.

All I've managed to ascertain so far is that the "JPEG library reports unrecoverable error" part of the message comes from the gd library (gd-jpeg.c), and the "JPEG parameter struct mismatch: library thinks size is abc , caller expects xyz" from the jpeg library (prototype found in jerror.h).

Cheers,
Rob
