I have OwnCloud 9.1 on a VPS. It works fine, however, in the gallery I have seen there are some issues with some JPG files. I found that some other users have similar problems, but I found no solution so far and would like to ask whether somebody knows what causes the problem.
I have a folder with a lot of holiday phorographs. Most of them are displayed well (thumbnail as well as preview when clicking on the file), but some are not. When I download the files which are not correctly displayed, I am able to open them in any viewer program (Paint, Photoshop, Gimp, whatever), only ownCloud has problems with these files. I found out that it did not like the capital case JPG extensions, so I renamed all the files to .jpg, and now, some more files are displayed correctly, but still not all of them.
How can I find out what the problem with the JPG images is, and is it possible to fix that somehow?
I don't like this behaviour because it fills the ownCloud log with error messages (imagecreatefromjpeg(): gd-jpeg, libjpeg: recoverable error: Invalid SOS parameters for sequential JPEG
