I'm not sure why this is so difficult under Ubuntu/Linux. With Windows if I rotate an image in Windows Explorer or Window's image viewer, it retains that orientation everywhere in every application. But with Ubuntu some applications rotate and save that rotation, but the rotation is ignored by other applications and visa versa.
My main problem is that I can't seem to get the orientation of my photos to be set correctly and the honored by all applications. Apparently I hold my phone in different orientations when taking pictures and I'd like to fix them once and for all. But there doesn't seem to be any simple tutorial on how to do this, just random posts about command line picture editing which doesn't work if I have to open the images up in a viewer, then close and run a command on them and open them up again to check... This is madness.
The best I can find is cryptic discussions of Exif data, without any clear novice instruction.
Does someone have a simple tutorial on how to do this simply and permanently so that I can get my 1000's of pictures corrected once and for all?
Thank you
