This picture was taken after the band found out about ringo's true nature (being an octopus).
You can see in george's facial expression his disappointment and shock.
He is trying to kill Ringa, but fails because of Ringa's psychic powers.
On the left side of the picture, you can see Paul getting ready to punch Ringa.
At the bottom, you can see John reading a book titled
"1000 ways to identify an octopus"
This is clearly a mark that Ringa is in fact, an octopus!
