What is the greatest photo of all time?

[partygirluk]

Or just, post a great photo. Sorry to be anal, but please don't post gross out or hot lady photos, they have their place, but in a different thread. I am looking for photos with "wow" factor.

I don't know how to post images, but if someone could this for me, I would be grateful. My vote goes to a photo from Vietnam. Some young Vietnamese man is being shot by a general. The photo is taken as the photo is halfway through his head. It entered via the right hand side of his body, but you can see that it his left hand side of his body that is dead, whilst the right hand side seems normal.
