I believe the answer is:

enlarge

I'm a little stuck... Click here to teach me more about this clue!

'up a picture?' is the definition.
'enlarge' can be an answer for 'up' (thesaurus). I am unsure of the 'a picture?' bit.

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for enlarge that I've seen before include "Amplify" , "Make big" , "Wax" , "Stretch" , "Make greater" .)

I've seen this clue in The Globe and Mail.
