I know how...I'm not only useful for story 
I'm guessing you want images in the background and credits on the screen correct? To music?
Make the images background pics and fill a map with that pink crap that is see through when you go into the game...now set an event to auto start the music and type in all of your credits, you can make them appear at the top, middle, and bottom and transparent with the little options. Now, make your party invisible and have them warp in at the center of the map...when you want to switch images simply warp them to another map with a different background...or maybe just change the background it's been awhile since I used the program so I can't remember if you can change backgrounds...
Anyway I think that should do it. If you want to make the credits scroll or something you'll have to talk to MA. Hope it helped.
Curse you stumble button!
