and its best to load larger images into the SWF instead of embedding them, to speed up the SWF loading time
What did you mean by this. How does it make sense to load larger images into the swf. You lost me there :-)
also there is nothing in the export properties.
The problem that i am facing is that i am importing 600 pngs. Then for some strange reason flash treats them as JPG's unless i individually change the settings. By this i mean .with each one of the 600 images. This is a nightmare. The reason I need flash to treat the png pics as they are is because when it changes them to jpg...it increases the sizes by more than 2
