I copied some photos taken with my N9 from the phone to a computer via USB without editing them in the phone first. Now I can't open any of those images with GIMP (version 2.6.11, running on Ubuntu Studio 11.10).
When I checked the file type of the images in a terminal, it says "JPEG image data, EXIF standard". I thought this might be the problem, but GIMP opens images taken with my Canon camera totally fine, and they're in EXIF as well.
So I wanted to rule out the possibility of the image size (3552x2000 pixels) being the problem, and resized one of my photos in N9 before copying it to the computer again. GIMP opened it with no problems. However, I noticed that now the image type was "JPEG image data, JFIF standard 1.01". Next, I tried editing ("autofix all") a photo in N9 without resizing it, then copying it. It was the original size (3552x2000) but the format was now JFIF again, and GIMP was totally happy with it.
So now I'm wondering what could be the problem. It might have nothing to do with phone whatsoever. However, as EXIF images taken with a digital camera work, I'm wondering if N9 writes the EXIF data in a somehow different way than other devices. Also, why does it save the picture using two different standards depending on whether the image was edited or not?
Ok, thanks for the info.
It might very well be a problem related to Ubuntu (or Gimp in Ubuntu). Other programs (such as Comix which I use for viewing images) seem to open the files fine, so there's something special about this combination anyway. I also use the default settings in the camera software (i.e. large size etc.), so I don't think I've managed to mess up anything myself when taking the photos.
The problem occurs on OS X as well, using Gimp 2.8.0. One possible way to work around it is to change the Select File Type option from Automatically Detected to JPEG image, although this may not work on all builds. (please note that the Select File Type section is not the same as using the dropdown menu that is set to All files as a default)
It seems this bug hadn't been reported on the Gimp bug tracker so I've added it there, let's hope this gets fixed sometime in the near future. https://bugzilla.gnome.org/show_bug.cgi?id=677759
