This is an entry for a so-called publicity still. It's (very likely or proven) just a picture form promotion reasons since there is no spanking scene in the movie itself (or it has been cut).
REMARKS
There is no spanking in this movie, but a spanking threat. ‘If it weren’t for my pension, I’d wallop her. You’d better take over.’ (police sergeant to the father).
This might be just a publicity still to go with it or a scene that has been cut from the final version
