I've not ever seen this error message before, but a co-worker is getting the
following (v3.10 ... will upgrade her soon). What does it mean?
Error: "Open error when decompressing" (-1) at link
www.s2h.tas.gov.au/2001/gallery/displayImage.php?id=184
(from www.blahblah)

Actually, her whole capture went quite badly, but we'll have a shot at it
again.
