Search for an image (4)
I believe the answer is:
look
I believe this clue is a double definition.
'search for' is the first definition.
(thesaurus)
'an image' is the second definition.
(thesaurus)
(Other definitions for look that I've seen before include "Inspect" , "Facial expression" , "View" , "See - air" , "Behold" .)
