Hmm, 3 menu items to do the 'same' thing. Sounds like the UI is too
complicated. How about
o One rotate/flip menu. Depending on mimetype digikam
decides which method to use as long as it's an lossless
operation. Decision critria: speed.
o when there's no lossless operation available inform the
user with an dialog with  don't show this message again
for the filetype x/y
If this makes sense for others too, I'll submit an wish list report
in case it does not exists already ;)

To me vi is Zen. To use vi is to practice zen. Every command is
a koan. Profound to the user, unintelligible to the uninitiated.
You discover truth everytime you use it.
