Record in photo book (5)
I believe the answer is:
album
This clue is a double definition.
'record' is the first definition.
(I've seen this before)
'photo book' is the second definition.
(I've seen this before)
'in' is the link.
(Other definitions for album that I've seen before include "Recording; book" , "CD, say" , "Book for stamps/photos" , "LP, perhaps?" , "Book of snaps" .)
