problem opening certain jpeg's from a canon dslr
I am having trouble opening certain jpeg's from my canon camera. I can open the jpeg's in other applications such as Irfanview and MS Paint, but have no luck with gimp. Note that this is only happens with certain jpeg's from my camera, I can open most of them no problem. gimp simply freezes when I try and do a file...open on these images. Also, both the working and non working pictures are roughly the same size, around 2MB. I have uninstalled gimp, deleted all associated files and cleaned the registry.

Yes the files are indeed on disk. The Canon is a Rebel T3i, less than one year old. I shoot in L Blocky and have a class 10 SDHC card.

Here is a link to three images on my public dropbox:

I just realized that all of the problem photos are longish exposures, although I can still open other long exposure pictures no problem.

Thanks for your help.

Same as Ofnuts, the files load OK in a linux machine. In a Win7 VM Gimp stalls. I thought about the metadata as well, looking at it in XnViewMP for example, the comment field is a bit strange. However removing all the metadata with XnViewMp was no fix, so maybe ExifTool writes a better file.

Converting the jpegs to tiffs with XnViewMP does save the metadata, and they open in Gimp, but even with some compression they are big files.

RE: problem opening certain jpeg's from a canon dslr
Thanks for everyone's input on this. My current solution to be able to edit the files in Gimp is:

1. Start the Task Manager, open Processes tab
2. Start Gimp, open corrupted JPEG
3. Stop the Metadata.exe process in the Task Manager

The JPEG should now open. An error message will briefly flash in Gimp.

I will look into changing Exif data on my Canon and will report back if I find a proper fix. If not this solution at least allows me to keep using Gimp for photo editing.
