Free issue featuring reversed image (10)
I believe the answer is:
emancipate
'free' is the definition.
(I know that emancipate is a type of liberate)
'issue featuring reversed image' is the wordplay.
'issue' becomes 'emanate' (both can mean to give out or radiate).
'featuring' means one lot of letters goes inside another.
'reversed' says the letters should be written backwards.
'image' becomes 'pic' (short for picture).
'pic' in reverse letter order is 'cip'.
'emanate' placed around 'cip' is 'EMANCIPATE'.
(Other definitions for emancipate that I've seen before include "Free from restrictions" , "Liberate" , "Free from slavery" , "Set free" , "setting free" .)
