The PNG format can hold alpha transparency which can be read and used by
Flash 3.

If you're using Fireworks, then Flash can open a native Fireworks file,
because Fireworks uses PNG as its native file format. I'd recommend doing a
"millions of colors" PNG export from Fireworks, however, to get rid of the
editing data which Flash doesn't really need.

If you're using another tool, such as Photoshop, doublecheck its
instructions on creating PNG with alpha information. Yu can always import
this file back to the host to check how it's saving out its PNG.

In all tools, semi-transparent bitmaps will cost you quite a bit in
filesize... doublecheck the size of the file. If you can, consider trying
to use Flash's built-in image tiling, in order to cover a larger screen
area with a smaller number of source pixels.

(The alpha-transparency for native vector curves is almost free in
comparison to pixel-based graphics... if you can design the piece so that
the transparent element is a Flash painting then that will give you much
faster download times.)
