In the pictures, it’s great! (4)

I believe the answer is:

epic

'great' is the definition.

'in the pictures it's' is the wordplay.
'in' says the answer is hidden in the clue.
'EPIC' is hidden within 'the pictures its'.

(Other definitions for epic that I've seen before include "Heroic narrative verse" , "Long, heroic story" , "On a grand scale like long poem" , "Blown up" , "Long poem/story" .)

I've seen this clue in the Evening Standard.
