[plt-dev] Which image.ss?

When you choose "Add teachpack..." from the "Language" menu and select "image.ss" is it supposed to use htdp/image or 2htdp/image? If the latter, why does this:
   (bitmap "tugboat.jpg")
produce the error:
   bitmap: name is not defined, not a parameter, and not a primitive name

while, if instead of using the teachpack dialog, you use "require":
   (require 2htdp/image)
   (bitmap "tugboat.jpg")
it works fine.
