Apollo 10 was the fourth manned Apollo mission, and the second manned mission that went into Lunar Orbit. Its goal was testing all of the components and procedures, just short of actually landing. In reality the Apollo 10 mission did never leave Low Earth Orbit. The photographs of the moon were most likely made by earlier unmanned lunar explorations, retouched and relabeled Apollo 10. This will become clear when you read this article Apollo 10 Backside of the moon, where Apollo 10 Astronaut Cernan makes a big mistake on the "backside" of the moon.
