Is there anyway I can make windows recognize the correct orientation and set the wallpaper accordingly? The wallpapers are set to change every 20 minutes.
I think that this is your answer. In normal mode, i.e. holding the camera in the standard landscape orientation, the X-axis is the horizontal and the Y-axis is vertical. The meta data records it as such. However, when you turn the camera 90 degrees to take a portrait photo, the meta data records the X and Y information as they would be if the camera was still held in the landscape orientation - in other words, the X-axis and Y-axis are effectively swapped. Some cameras are capable of intelligently assigning X and Y according to the orientation, either manually or automatically. Most cameras don't have this capability, so orientation correction needs to be done afterwards by means of an editing program.
