[racket] Programatically loading bitmaps with 2htdp/image

Is there a way to do something like this:

(define (make-frame t)
  (bitmap (format "~a.png" (add1 (modulo t 13)))))

(animate make-frame)



This code gives me:

bitmap: expected the argument to specify a local path (via a string) or a
module path (e.g. `icons/b-run.png')
