I happen to came across below stated sentence in an English preposition book.
"This photo is her with her best friend."
I assume, that grammatically correct sentence should be:
"This photo is of her with her best friend."
To me here of means: "indicating an association between two entities, typically one of belonging, in which the first is the head of the phrase and the second is something associated with it.
I am not native English speaker. Is it something to do with AmE and BrE? or I lack understanding of sentence structure :(
