I loaded a ton of photos over the last few months and every time I did the group of photos would be named by the date the photos were taken. I finally got around to backing up and updating my IPad and now all the dates have been replaced with "157IMPRT" and "158IMPRT" and so on. I liked the dates because the photos are of my 2 year old son as he has grown up. Any easy way to get the dates back? I don't understand why this would change. Any help would be greatly appreciated.
