Important person in recently taken photograph (7)
I believe the answer is:
hotshot
'important person' is the definition.
(I've seen this before)
'recently taken photograph' is the wordplay.
'recently taken' becomes 'hot' (referring to stolen goods).
'photograph' becomes 'shot' (shot is a kind of photograph).
'hot'+'shot'='HOTSHOT'
'in' is the link.
(Other definitions for hotshot that I've seen before include "Top player" , "Important person" , "Expert" , "ace" , "successful type?" .)
