Make another picture of French city's unfinished condition (7)

I believe the answer is:

reimage

'make another picture of' is the definition.
(make an image of again)

'french city's unfinished condition' is the wordplay.
'french city' becomes 'reims' (city in France).
'unfinished' means to remove the last letter.
'condition' becomes 'age' (condition can mean age or level of damage).
'reims' with its final letter taken off is 'reim'.
'reim'+'age'='REIMAGE'
