Hello,

I've tried it on couple of images and on some of them eog preserved 
EXIF data, whereas on others it did not. I have not yet found the 
condition which influences this behavior.

For pictures on which eog does not preserve EXIT data, it looks like 
this:

before:

[erazim ~]$ jhead /home/media/Pictures/prvnich\ 430\ fotek/pict0400.jpg
File name    : /home/media/Pictures/prvnich 430 fotek/pict0400.jpg

after rotation and saving in eog it looks like this:

[erazim ~]$ jhead /home/media/Pictures/prvnich\ 430\ fotek/pict0400.jpg
