'image?' is the definition.
(I know that image can be written as icon)

I don't understand how the rest of the clue works.

(Other definitions for icon that I've seen before include "Admired figure" , "Figure of Christ in Eastern churches" , "Sacred image or picture" , "Uncritically admired object" , "representing a saint?" .)

I've seen this clue in The Globe and Mail.
