Konqueror makes use of EXIF Image Orientation information.
It only affects how Konqueror DISPLAYS the image.
If this tag is changed the image will be rotated accordingly
(when viewed in Konqueror).
Since konqueror does rotate the images according to this tag
when viewed. The only thing konqueror has to do to rotate
an image is to change the value of this tag!

The name Digikam::exifRotate has confused me. I thought it ment
"rotate by modifying exif info" when it really meant
"rotate image according to exif".

To solve most problems digikam should honor the EXIF Image Orientation
tag, it can be read by using libexif.
