The most obvious issue is that it's an alleged picture of a ghost, and ghosts aren't real.
Off topic:-
Here's a little story about a ghost.
A few years back at work (in a jail) one of the staff decided to try and fool everyone by staging a poltergeist on cell camera.
He tied a bit of string around a bucket handle and left the bucket in an empty cell, with the string trailing out under the cell door and across the landing where it's easily pulled without being spotted opening the door on camera,
He waited for a day and made sure nobody entered the empty cell, and then pulled the string - sending the bucket flying across the floor.
This was all perfectly caught by the video recorders on the wing and it wasn't before long that the word went around about this ghost and nearly everyone in the jail went to watch the replays of this footage.
Now, we have a few women staff at our place claim they have a special gift, an ability to see spirits of dead prisoners and staff wandering around the landings at night. In the past they've claimed they talk to these spirits and got information from them.. real barmpot stuff.
Anyway, one of these crackpots came to view the footage of the ghostly flying bucket. She jumped on this footage as evidence that what she's been saying all along is true and immediately claimed it was an angry soul of a prisoner who had died on the wing (the jail is 200+ years old and they used to hang people there).
To the amazement of everyone around, she then claims the spirit is standing with us watching the footage and she starts having a conversation with it.. telling it to go to the light. Then she decides that the best way of ridding this spirit from the jail is to walk it to the main gate.. which she does, all the way there having a conversation with this invisible entity.
We haven't told her it was string tied to a bucket.
I guess if there's a moral of this story, it's that the people who shout loudest about ghosts are the biggest gullible morons on the planet, and yet normal people are quite happy to believe in them without evidence.
