I have this problem with JPEGs that come from my digital camera, a Canon
A510. When I put the camera on its side to take portrait-oriented
photos, the Canon saves them as landscape with an EXIF "rotate" tag.

Some software honours this, and rotates the picture when it is loaded.
But not everything does. For example, if I try to load one as a
background picture in Gnome, it will come out "landscape".

You could file a bug against the screenshow, or automatically rotate
such pictures when you import them.

I have a shell-script I run from cron that changes the backdrop to a
random image periodically. I use the following code, with ImageMagick
and the jhead RPM from Extras, to automatically rotate these pictures:

if jhead "$PICTURE" | grep -q "entation  : ro"
then
    COMMAND=$(jhead "$PICTURE" | grep Orientation | cut -c16-)
    nice -20 convert -$COMMAND "$PICTURE" $HOME/.background-img
    PICTURE=$HOME/.background-img
fi

(It relies on the output of jhead being nearly suitable as a command for
convert).

You might want to modify this for your purposes...

Hope this helps,

James.
