Behind every photo is the life story of the people in it. As the old saying goes, a picture is worth a thousand words. You preserve priceless memories for generations to come when you upload a photo to the Family Tree and Add What You Know about the people in it.    Upload a photo for World Photography Day, and then Add What You Know to preserve the story behind it. Comment PHOTO to get started.    #worldphotographyday #addwhatyouknow #familyphotos #familyhistory
