Ok, no one answers.
Please consider this thread as a feature request.
Meantime I found a workaround.
I create an entry in
Send To (external) to
NConvert, a command line images tool
nconvert.exe -overwrite -rotate 90 "[Filename]"The problem is that MediaCenter takes a long time to update and show the image now rotated.
Also, is it possible to associate a shortcut to this action?
