Type of sketch taken from thin album (9)
I believe the answer is:
thumbnail
'type of sketch' is the definition.
(I've seen this before)
'taken from thin album' is the wordplay.
'taken from' indicates anagramming the letters.
'thin'+'album'='thinalbum'
'thinalbum' anagrammed gives 'THUMBNAIL'.
(Other definitions for thumbnail that I've seen before include "Small image" , "computer image" , "Brief description" , "Digital process" , "type of sketch" .)
