The picture contained story (4)
I believe the answer is:
epic
'story' is the definition.
(I have seen 'Heroic story' mean 'epic' so perhaps 'story' could also mean 'epic')
'the picture contained' is the wordplay.
'contained' indicates a hidden word.
'EPIC' is hidden in the letters of 'the picture'.
(Other definitions for epic that I've seen before include "Ben Hur, say" , "Blown up" , "Colossal" , "Tale of heroic deeds" , "Long literary work about great events" .)
