In the final shot we see Jack’s face airbrushed into a picture that's dated 1921. Many believe Jack Torrance, the caretaker in the movie, is a reincarnation of the person in the photo. This cannot be for 2 very good reasons 1) the definition of the word is very precise; reincarnation - the rebirth of a soul in a [new] body. Jack is still the same person. 2) Stanley Kubrick makes it obvious with the palm tree dead center that it’s not The Overlook. The photo is not proof that Jack has ever been at the hotel before because the place depicted isn’t The Overlook.
