Medicine man shows pictures (6)
I believe the answer is:
cinema
'pictures' is the definition.
(I've seen this before)
'medicine man shows' is the wordplay.
'shows' indicates the answer is hidden within the clue.
'CINEMA' can be found hidden inside 'medicine man'.
(Other definitions for cinema that I've seen before include "Odeon perhaps" , "Films, collectively" , "Film industry" , "Silver screen" , "The flicks" .)
