Most of the time, when someone takes a photo, there is a reason for it to be taken. More often than not, photos are pretty self-explanatory. Many photos explain themselves, but others need context. Context is important for many reasons. Context could be a title or a short description, and it gives a photo a reason to be. Not everything needs context, though, sometimes adding some wonder into the world is a good and healthy thing. Unexplainable, useless, pointless, and otherwise odd photos add mystery to the world, and that's a great thing.
