Picture of Bill next to the water in Biarritz (7)
I believe the answer is:
tableau
'picture' is the definition.
(a tableau is a picture or display)
'bill next to the water in biarritz' is the wordplay.
'bill' becomes 'tab' (a tab is a bill at a bar).
'next to' means one lot of letters go next to another.
'the water in biarritz' becomes 'l'eau' ('the water' in French).
'tab'+'leau'='TABLEAU'
'of' is the link.
(Other definitions for tableau that I've seen before include "Motionless group on stage" , "Pageant" , "A dramatic or picturesque scene, may be still" , "Painting - spectacle" , "Scene of still figures" .)
