Yeah ... No.
I'm generally not a fan of party politics (though I realize you often have to bite the bullet on voting). But the pirate party here (Germany) is a really problematic bunch some of them thinking freedom means free markets some of them thinking free speech means they should be able to say hateful Nazi shit ... Really not a party I want to vote for, even in a pinch.
So ... I was also interested by that question and intrigued by that photo, so I put on my research cap and went away.
From what I found out it seems to be both:
A staged photo/shot but from a historical movie called Dr. Mabuse the Gambler .
I was able to find the movie on YouTube with A seance scene which however does not seem to be the same scene (or at least a different angle) from the picture. If anyone has the time to scroll through all 4h of that movie the scene in the picture might be in there.
