I'm left handed. So, I take my iphone photos using my left finger. My iphone intuits which side should be up when I am viewing photos on it. However, when I import to Photos folder on my Windows desktop, often the photos are displayed by DF upside down. I've tried a number of ways to change them, and--while some work--I can never figure out why. Is there a sure fire way to set the orientation so that when DF reads the file, it shows correct?

Also, I never know whether one is upside down til it displays. is it possible that once it displays the first time, none of my subsequent changes to the file rectify the problem once DF has "swallowed the image" the first time?
