I'm sorry, I was convinced that the image-magick suite would be enough
for tumme's image manipulations but now I see that you mentioned
jpegtran in the manual.
Lets see what the respective debian package name is:
$ apt-file search jpegtran
libjpeg-progs: usr/bin/jpegtran

Why can't you just use convert? It's needed for the image-dired
thumbs anyway, is it too slow?

OK, installed libjpeg-progs and it works now, thanks. But its a bit
awkward since I'm constantly asked whether I'd like to change the
original file and when I decline the rotated display is again
reverted. I could imagine that this becomes very annoying when
displaying stuff from a read only drive.
Does it make sense to check the existence of the needed image-magick
and jpegtran executables with the Emacs configure script?
And it would be helpful if the error message could give a hint which
kind of executable is missing.
