I have a very difficult time trying to arrange pictures with only being able to see a tiny photo when uploading the pictures. There used to be a preview with a larger view of the photos that allowed you to arrange photos before posting them but that has been taken away. Can you add the feature back please. It is so time consuming going back and forth arranging photos because they are in the wrong order.
