 basic approach is: "send message in x seconds", so you do something like:

on displayImage
  -- put code to display image in place of this comment
  send "fadeImage" to me in 1 second
end displayImage

on fadeImage
 -- put code to fade the image 1 step towards invisibility in place of
this comment
  if (not FullyInvisible) then send "fadeImage" to me in 10 milliseconds
end fadeImage

where "FullyInvisible" is a check for whether you have fully faded the
image or not (true in you have, false if not)
