Poster recruiter redesigned, bringing on image consultant (7,8)

I believe the answer is:

picture restorer

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

'on image consultant' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'poster recruiter redesigned' is the wordplay.
'redesigned' indicates an anagram.
'poster'+'recruiter'='posterrecruiter'
'posterrecruiter' anagrammed gives 'PICTURE RESTORER'.

'bringing' acts as a link.

Can you help me to learn more?

(Another definition for picture restorer that I've seen is " One improving Old Masters".)

I've seen this clue in The Independent.
