'picture' is the definition.
(thesaurus)

'shows r2 boarding boat' is the wordplay.
'shows' becomes 'two' (I can't justify this - if you can you should believe this answer much more).
'rw' becomes 'r'.
'boarding' is an insertion indicator.
'boat' becomes 'ark' (ark is a kind of boat).
'two'+'r'='twor'
'twor' put inside 'ark' is 'ARTWORK'.

Can you help me to learn more?
