i am having the same problem with trying to rotate a picture once it has been imported the desktop , i have notified apple about this problem, if i have a picture that is upside down i try to rotate it but when i move to the next pic i get the error msg that there is a problem with the photo,s file properties.
apple have advised me that its something wrong with windows 7 , and i should try it on a different computer, anyway i hav tryed the same thing on the laptop which is using windows xp and im still getting the same error message , so its got me buggered !
This problem did not happen with my iphone 3 nor did it happen with my iphone 4 , the 4s is the one it wont work !
so whats going on apple ?
