Illustration from India engraved in copper (3)
I believe the answer is:
pic
'illustration' is the definition.
(short for picture)
'india engraved in copper' is the wordplay.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'engraved in' is an insertion indicator.
'copper' becomes 'pc'.
'i' put within 'pc' is 'PIC'.
'from' is the link.
(Other definitions for pic that I've seen before include "Image (abbr)" , "Photograph (colloq.)" , "film" , "Photo (colloq.)" , "Photo (informal)" .)
