Photos capturing house in French or US capital (7)
I believe the answer is:
phoenix
'us capital' is the definition.
(state capital of Arizona)
'photos capturing house in french' is the wordplay.
'photos' becomes 'pix' (short for pictures).
'capturing' indicates putting letters inside.
'house' becomes 'ho' (abbreviation for house).
'in french' becomes 'en' ('in' in French).
'ho'+'en'='hoen'
'pix' placed around 'hoen' is 'PHOENIX'.
'or' acts as a link.
(Other definitions for phoenix that I've seen before include "Legendary bird born from ashes" , "capital in America" , "part of Arizona" , "Legendary Arabian bird" , "Reborn bird" .)
