Grew into a photograph? (9)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
developed
'grew' is the definition.
('develop' can be a synonym of 'grow')
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for developed that I've seen before include "complex perhaps" , "Like film suitable for viewing" , "mature" , "Caught" , "Grew, progressed, evolved" .)
