I'm given long time to make picture (5)
I believe the answer is:
'picture' is the definition.
(I know that picture can be written as image)
'i'm given long time' is the wordplay.
'given' is a charade indicator (letters next to each other).
'long time' becomes 'age' (an age is a period of time).
'to make' is the link.
(Other definitions for image that I've seen before include "Purplish pigment; pool" , "Metaphor; figure" , "Copy" , "Representation of person or thing" , "Visible representation" .)
