Depending what graphics program you work in. If you create and image with a

transparentbackground and save it as png, then import it into Flash, flash will

read the transparency and only

the image will appear. If you save it as jpg or bmp and then import it into

flash, flash will read the

existing BG color and therfore you wont have a transparent background.


As far as the way Flash exports it I always thought that any graphics where

exported as

a jpg. But somehow if the original imported graphic was png then it keeps the

size of the

alpha. Kinda like if I where to paint an image on acetate and mail it to you,

I would have to pay the postage for the weight of the transparency too, even

though you couldnt

see it.


The way flash exports is still part of a mystery to me.
