You can make a simple alpha fade. Convert your background image to a symbol, then make a movie where in the first frame, the alpha value is set to 0%, and in the last it is set to 100% (or whatever you like). Then click on a frame in between those two and select Motion Tween.

Oh, and you’ll want to put a layer of ActionScript in with a keyframe at the end of the tween containing a stop() action. Otherwise your fade will loop.
