Fortunately, there are already several command-line tools available for that, as well as several GUI tools that have some kind of batch mode. One example of such a command-line tool is Jhead. You can either use the option "jhead -autorot" to rotate the image and clear the EXIF Orientation tag, or use the option "jhead -norot" to clear the EXIF Orientation tag without rotating the image, assuming that some broken program has already rotated the image without updating the EXIF info. I have also seen some shell scripts that use the command-line "exif" program to change the value of the Orientation tag directly. So there are already many ways to fix the JPEG files with EXIF info that have been incorrectly handled by some programs (such as GIMP 2.2, but hopefully not 2.4). Although I think that option (1) above should be the default instead of (2), I think that (2) can still be useful in some cases. Some of the EXIF-aware image editors that I looked at are also offering an option to ignore the EXIF Orientation tag (this is never the default, though). Bill has already written the code for asking the user, so let's not throw that away. So the default should be to open the images with the correct orientation without asking, and there should be an option in the preferences (gimprc) that allows the user to ignore the EXIF Orientation tag or to be asked every time. The threshold for adding new options to the gimprc should be high, but I think that this one deserves it. -Raphaël
