Preloader for all xml data

I desperately need to preload everything that’s in my xml document, images and all, before my movie starts.

My movie displays one picture at a time, fades it out, and fades in another (from the next node) and so on. The way I’ve built it, it doesn’t call for the next image until it’s needed. The problem with this is the download lag doesn’t allow the images to fade in/out together and the wait results in a white space. I put in my old school preloader, but it only looks at what’s in the flash file, ignoring what will be imported via XML.

I’ve attached my fla and xml, any help would be greatly appreciated.
