Re: "Unrecognized image file format" error when loading JPG file

[Benjamin Kopic <benjamin kopic panContext com>]

Hi Jens

I just noticed something when I opened "Open file..." dialogue. In "Determine File Type:" combo list I do not have JPG file format (my default option is "By Extension"). Could this have anything to do with this?

Also, I tried finding any 16 bit JPG files on the net to try and see if I can open them, but I could not find any (if you have one, could you please e-mail it to me).

In addition, I have submitted this to bugzilla.gnome.org: BUG#126672
http://bugzilla.gnome.org/show_bug.cgi?id=126672

Best regards

Ben
