Lets break this down, the reason we haven't gone back to the Moon is because we've learned all we can for now, it's very expensive to just fly there for shits and giggles. The picture he's talking about, is from the training exercise three people were taking part in before they actually went to the Moon. The "guy on the Moon" by which he means NEIL ARMSTRONG, operated the camera, it was a Westinghouse TV camera that was attached to the MESA (Modular Equipment Stowage Assembly). Armstrong set up the camera through a lanyard which deployed the MESA with the camera attached to it and then Buzz Aldrin (the second Astronaut who went with Neil and would be the second person to walk on the Moon) turned on the camera from inside the ship.
This is why the Internet should require some kind of IQ test before use it. It stops retarded shit like this from being spread around.
FUN FACT: The picture in question of the three Astronauts "on the Moon" without their helmets was a picture of John Young, Thomas Mattingly, and Charles Duke. Two of the thre (John and Charles) would eventually end up going to the Moon. The picture itself was taken in February in 1972 where the would end up taking their trip two months later in April.
