if you start thinking/working on this, some data from EXIF
might be interesting and helpful too, esp. the "Orientation".
using that data, automatic rotation to the "correct" orientation 
would be possible.

what about color space infos ?  
or time stamps or GPS data which might be used to be typeset...

that would be great as my current \message{} stuff is far from being perfect...
