[racket] multiple images problem

Here is a high-riding American SUV, does this help? 


(require 2htdp/image)

(define cab  (beside (rectangle 33 18 'solid 'red) (right-triangle 10 18 'solid 'red)))
(define body (rectangle 100 30 'solid 'red))
(define top  (above/align 'right cab body))
(define tire (circle 15 'solid 'black))
(define bot  (beside tire (rectangle 25 10 'solid 'white) tire))

(above top bot)
