Some nice pictures can be classic (4)
I believe the answer is:
epic
'classic' is the definition.
(I've seen this before)
'some nice pictures can' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'EPIC' is hidden in the letters of 'nice pictures can'.
'be' is the link.
(Other definitions for epic that I've seen before include "Nonsense, rubbish" , "Vast in scale" , "blockbuster" , "Long, heroic story" , "Of heroic proportions" .)
