All the same, it's a picture (5)
I believe the answer is:
still
I believe this is a double definition.
'all the same' is the first definition.
('still' can be a synonym of 'all the same')
'a picture' is the second definition.
(still is a kind of picture)
'it's' is the link.
(Other definitions for still that I've seen before include "sort of life" , "... [STRONG LIQUOR] produced by this" , "Static photograph" , "Even now; not moving" , "Source of alcohol" .)
