In Files 3.10.1 (formerly Nautilus) I display thumbnails when viewing a folder of images. If the orientation of some images is wrong (i.e. landscape format displaying as portrait, or vice versa) I rotate the image to correct the orientation, and save the file when I close it. Sometimes the corrected orientation is represented by the thumbnail, but sometimes the thumbnail remains incorrect.

I have deleted ~/.thumbnails/fail

I have run rm -r ~/.thumbnails

I have refreshed using F5

There is another odd symptom, which may help explain the problem to someone. Suppose I have an image that appears as a thumbnail wrongly oriented, rotated 90 degrees clockwise. So I open and rotate the image 90 degree counter-clockwise to correct the orientation. The thumbnail still displays with the wrong orientation, but when I open the image using Files it is correctly oriented. If I open it in GIMP, however, it has the wrong orientation. It seems as if Files has not really rotated the image file, but knows that it should display it rotated when it opens the image. (But GIMP does not know that it should display it this way).

  • I suggest you carefully review the answer by Javier Rivera.

    I strongly suspect that this has to do with EXIF data. Nautilus auto-rotates images that have their orientation saved on their EXIF data if I'm not mistaken.

  • You could well be right, Hakermania. But in that case there is a weird discrepancy between what Files/Nautilus (and GIMP) sees as the correct way to show the image, and what Image Viewer sees to be the correct way. Any ideas, anyone?
