How do I import/read images and their ID from a separate folder to change the icon of a button?

Not exactly like that, but you can create image objects that only reference an stored image somewhere, by setting it's fileName. So you could have a button that references an id of an existing image object, which in turn references an image on your hard disk. I suggest to look up the fileName dictionary entry, barring that, here's an example (untested):

on mouseUp
  create image
  put it into theImageID
  create button
  put it into theButtonID
  set the icon of button ID theButtonID to theImageID
  answer file ""
  if it <> "" then
    set the fileName of image ID theImageID to it
  end if
end mouseUP
