Online contributor printed picture (6)

I believe the answer is:

poster

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

'picture' is the definition.
(I have seen 'Large picture ' mean 'poster' so perhaps 'picture' could also mean 'poster')

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for poster that I've seen before include "Large printed bill" , "surfer who leaves messages on boards?" , "Paper advertisement for topers" , "Person who sends" , "Largfe public notice." .)

I've seen this clue in The Irish Times.
