Question

Is this sentence OK? Or how would you say it?
(on te wall, on the table)

Wasn't there a picture here?

Answer

apart from the obvious missing 'h' in 'the', I guess the only thing I would do is to change the 'here' into 'there'. 
It would be likely that if you said that - you would be pointing to where you thought it was, and therefore 'there' would be more natural.
