[plt-scheme] image-snip initialization

Thanks for the previous response.  Let's try this again.

(define Image-Snip%
    (class* image-snip% ()
      (super-instantiate ())))

(define Image (make-object Image-Snip% "/Users/dr/test.jpg" 'jpeg #f 
#t))

This fails, but I really don't understand how or why.
