Sorry..I don't quite understand...:)
"Both 0.8.x and 0.9-svn" means both versions are possible?
As I see in the Configuration/Embedded Info panel I have to select the "Rotate
images and thumbnails according to EXIF tag" and the "Set EXIF orientation tag
to normal after rotate/flip" options to have a physically rotated picture.
About the rotation: Is it done in a "losless" way? Or with recompression?
Actually in my opinion the real rotation of the picture during the downloading
phase is better (only if it is possible to done without data loss), since some
of the image programs/viewers are still not dealing with the EXIF tag, thus they
will open a portrait horizontally.
