transparency flash movie OUTPUT_MOVIE=SINGLE/MULTIPLE

[Kristjan Annus]

Hi,

the link you sent me is usable only from your own computer, so I cant
see it.
I'll send you a link from my Flash test application (player 7 required).

http://www.tartu.ee/bi_kaart/tarkvarastuudio.html

The opening page swf map file is about 100k in size. The same picture in
jpg format in the same application is ~33k.
I use it in another flash movie, but every time when the client is
zooming a map he has to download about 100-300k
new map image.
