The new update automatically detects image orientation. It will then attempt to rotate based on the orientation of the camera that took the photo.
For instance if a person took a photo holding the camera vertically, then after the photo is uploaded to our server our software will attempt to read special information embedded in the photo/image file that is related to the orientation of the camera. Then based on that information our software on the server will rotate the image.
This has been a great update for some of our users.
