I'm a long time providing pictures (6)

Ross

I believe the answer is:

images

'pictures' is the definition.
('image' can be a synonym of 'picture')

'i'm a long time' is the wordplay.
'a long time' becomes 'ages' (ages can mean a very long time).
'im'+'ages'='IMAGES'

'providing' acts as a link.

(Other definitions for images that I've seen before include "Reflections in mirrors" , "Pictures, representations" , "visions" , "ideas" , "works by Debussy" .)
