Toss a coin for the picture (4)
I believe the answer is:
icon
'the picture' is the definition.
(synonyms)
'toss a coin' is the wordplay.
'toss' is an anagram indicator.
'coin' anagrammed gives 'ICON'.
'for' acts as a link.
(Other definitions for icon that I've seen before include "Very important person" , "Cultural or computing symbol" , "Image or figure venerated as sacred" , "Something revered" , "Russian religious image" .)
