Preloader and scroll plane

I need help with a problem, I am having problems getting images to scroll in flash. I have the images in a movie clip being loaded into a scroll plane, that works but in order for me to get the images to show up in the scroll plane I have to export the movie clip and have it load on the first frame. I can’t do this because I have a preloader and its messing up my preloader. Is there anyway I can load that movie clip later in the movie and still have it show up in the scroll plane.
Any ideas please let me know.
