Place to shoot a small picture (5)
I believe the answer is:
inset
'a small picture' is the definition.
(I've seen this before)
'place to shoot' is the wordplay.
'place' becomes 'set' (synonyms).
'to' means one lot of letters go next to another (I've seen this in other clues).
'shoot' becomes 'in' (I can't justify this - if you can you should give a lot more credence to this answer).
'set' after 'in' is 'INSET'.
Can you help me to learn more?
(Other definitions for inset that I've seen before include "Gore" , "Implant" , "Small diagram contained by larger one" , "Diagram within another" , "It could be stuck between pages" .)
