The picture contains a long story (4)

I believe the answer is:

epic

'a long story' is the definition.
(eg an epic poem)

'the picture contains' is the wordplay.
'contains' indicates the answer is hidden within the clue.
'EPIC' is hidden in the letters of 'the picture'.

(Other definitions for epic that I've seen before include "Long poem set in nice picture" , "major work" , "(Of) immense (proportions)" , "Long, heroic story" , "imposing" .)

I've seen this clue in The Daily Express.
