Breaking up solid images (5)
I believe the answer is:
idols
'images' is the definition.
(I know this)
'breaking up solid' is the wordplay.
'breaking up' is an anagram indicator.
'solid' with letters rearranged gives 'IDOLS'.
(Other definitions for idols that I've seen before include "Much-admired persons" , "objects such as the Golden Calf" , "False gods" , "Objects of worship" , "Graven images sometimes worshipped" .)
