Preload SWF (With Dynamic images)

I have a SWF called main which loads images.swf. In images.swf, this loads a few dynamic images. How can I preload images.swf with the dynamic images?

Let’s say images.swf loads 3 images of combined file size 120k and images.swf is 10k.

When *images.swf * is selected to load from main.swf, how can I preload the lot all at once and have the preloader loading the 130k?

Cheers
