I've responded to this once, but I would give what I think is another explanation. You cannot see any [i]pair[/i] of feet actually against the wall; foot-holes have been mentioned, but it would take more than this. Whilst. at the same time, you cannot see any pair of [i]arms[/i] out in the open; if they used some sort of foothold they would equally need a hand hold to be in this position. A point of interest is the torso of what appears to be a woman (?) wearing tight leggings and bare-footed and also a pair of pillows. It could be disputed to ensure whoever views the picture uses the person lying on the floor to give credence to what it's purporting to be.
In any case, it would be so much easier to Photoshop a picture to get the same results.
Below is a rather simplistic view of levitation without using anything other than brain trickery:
The second one below shows a picture that[i]has[/i] been manipulated in Photoshop. What makes this different, and obviously fake, is that our own minds tell us there's no such thing as what our eyes show us here and we don't think twice about it ...
