As the Flash 6 player is downloadable from the Macromedia Site, somebody found out a new and very wanted future feature of Flash 6: loading .JPG's dynamically into a flash movie.
Now check this out (it already works in Flash 5, but you need to use the version 6 player.
create an empty movieclip and name it "blank". then add this code to the first frame of your movie:
this will load a jpg (test.jpg, located in the same dir as the .swf) into the "blank" movieclip.Code:_root.blank.loadMovie("test.jpg");
God I love this program
