http://hkmdb.com/db/movies/images.mhtml ... ay_set=eng , and credits captures for crew, cast, too (Need some update)
Fun fact: Chang Ping (1) plays 'Brothel Madam' again, the 4th time in 6 movies 1977-1979 (Maybe Madame Liu is the fifth time, I'll check soon)
Replaced the wrong link

Added Tu Fu-Ping and Wang Li (6) (both uncredited)

I have reviewed the credits screens and updated a number of cast and crew here and corrected some errors.
