What does it mean that Jack appears in that old photo at the end of the movie The Shining?

In fact, there are related explanations in the encyclopedia, so you can refer to them. This is what I chose:

Old photos and colonialism, two seemingly unrelated concepts, constitute the most essence and memorable part of the whole movie. The last group of ambiguous and suspicious photos in the film really caused quite a controversy after the film was released.
