set of facial stimuli wanted

[BARRY MANOR, NO DOUBT.]

I'm looking for a set of standardised photographs of faces showing a variety of
emotional expressions (as well as neutral expressions).  The faces are to be
used in a study of perception of affect in schizophrenia.  If anyone know of a
series of faces which may be suitable feel free to let me know.
