Artist's image with donkey and duck (7)
I believe the answer is:
picasso
'artist's' is the definition.
(Picasso is an example)
'image with donkey and duck' is the wordplay.
'image' becomes 'pic' (I've seen this before).
'with' means one lot of letters go next to another.
'donkey' becomes 'ass' (ass is a term for a donkey).
'and' is a charade indicator (letters next to each other).
'duck' becomes 'o' (resembles zero - 'duck' in cricket).
'pic'+'ass'+'o'='PICASSO'
(Other definitions for picasso that I've seen before include "Spanish artist, 1881-1973" , "As cop is a Spanish painter" , "Pablo -, artist (Guernica)" , "Pablo . . . . . . ., great Spanish artist of 20th century" , "Pablo ,,,,,,,, great late Spanish artist" .)
