Picture found in the playground (5)

I believe the answer is:

slide

I believe this is a double definition.

'picture' is the first definition.
(slide is a kind of picture)

'in the playground' is the second definition.
('slide' is part of 'playground')

'found' is the link.

(Other definitions for slide that I've seen before include "Make mild fun of" , "Playground structure" , "Microscope glass" , "Trombone part" , "Playground item" .)

I've seen this clue in The Telegraph.
