My game runs smoothly, but when a bitmap is first loaded onto the screen (usually more than one at a time) it causes some lag. The lag doesn't reoccur until you exit the app and restart it. I am curious as how to preload these images before they appear on the screen so I can make it look smoother. Its all in one SWF (no external files), and the whole SWF is only 10 MB (probably under 20MB when completed).
How do I preload the images so they don't cause lag during game play? (Like load it on a transitioning/loading screen)
