I was sent an email with this photograph that is supposed to be Joseph Smith. I looked at all sorts of youtube videos about it (I definitely didn't find anything official on it- just speculation, no prophets or apostles are saying it is or anything)- I even came across a few more pictures reported to be Joseph Smith- I didn't care too much for the other ones- but I really love this photograph. So it might not be him, but I kinda think it is and thought someone else might like seeing the picture.
Here was the best video about the picture- just don't bother reading all those anti comments at the bottom.
