Photo Slideshow Using XML and Flash - Hide the preloader?

Hi,
I’m using Kirupa’s “Photo Slideshow Using XML and Flash” found here: http://www.kirupa.com/developer/mx2004/xml_slideshow.htm

I understand that each image pre-loads individually the first time the .swf is loaded (until the images are cached?).

I would like to hide the pre-loader progress bar (I’ll make it alpha 0) and have the previously loaded image stay visible until the next image is preloaded ---- then the fade transition can happen.

The goal is for the user NOT to see the pre-loader between each image.

Any idea how this could happen? My actionscript is still a bit newie!

Thanks!
