Cameras save all images in a landscape orientation, but the EXIF data can be used to indicate the orientation. Most modern file browsers use this data to orient the thumbnails accordingly. Thunar should also use the EXIF data to present thumbnails in the right orientation.
Created attachment 2333 Screenshot of Thunar In this screenshot Thunar shows thumbnails for 3 versions of the same photo: original.jpg - the origianl photo of a penguin GPicView.jpg - rotated by GPicView, so only the EXIF data of the orientation was changed GIMP.jpg - rotated by GIMP, so the image matrix was actually rotated As can be seen, only the GIMP version is rotated. I will attach another screenshot of the same pictures as thumbnailed by a different file manager.
Created attachment 2334 Screenshot of windows XP These are the thumbnails of same files in the same folder, but as viewed in windows XP. The GPicView.jpg thumbnail is presented in the portrait orientation that was set in the EXIF of the file.
@Hezy: Can you attach original.jpg and GPicView.jpg for me?

Created attachment 2336 A Penguin in Phillip Island, Australia. Picture rotated by GPicView This is the version that was rotated by GPicView, i.e. only the EXIF data was changed. Hezy Amiel CC-by-SA 3.0
Since you marked it as fixed: Does it work for you now? If so, in which version?
