Admission from one who does people’s picture? (4)
I believe the answer is:
icon
'picture?' is the definition.
(I know that icon is a type of picture)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for icon that I've seen before include "portrait" , "object of admiration" , "Devotional image (C, not K)" , "Russian religious image" , "Sacred painting or representitive figure" .)
