I'm taking a long time getting the figures (6)
I believe the answer is:
images
'the figures' is the definition.
('image' can be a synonym of 'figure')
'i'm taking a long time' is the wordplay.
'taking' means one lot of letters go next to another.
'a long time' becomes 'ages' (ages can mean a very long time).
'im'+'ages'='IMAGES'
'getting' acts as a link.
(Other definitions for images that I've seen before include "Likenesses or impressions" , "works by Debussy" , "Semblances" , "Mental representations or figures" , "Reflections in mirrors" .)
