image

I'm a little stuck... Click here to teach me more about this clue!

'representation' is the definition.
(image is a kind of representation)

I can't explain the rest of the clue.

(Other definitions for image that I've seen before include "Pictorial representation" , "of Kairos with Melchior?" , "Likeness, could be spitting" , "Dead ringer" , "Visible impression" .)

I've seen this clue in The Sun.
