Hi Richard,
In Photoshop, after you have made your jpgs, make Masks from
each one of them where
white represent your transparent areas and black your
visible image (you can do this
by creating alpha channels, paths or just simply quickMask techniques).
Convert these Masks first to GreyScale
(Image-->Mode-->GreyScale) and then to Bitmap
Image-->Mode-->Bitmap.
Just make sure that the Masks are imported into Director
immediately after each image
they refer to.
Hope this helps.
