ActionScript 2.0 :: Dynamic Slideshow - Loading Images Using XML Info From Array

I've constructed a dynamic slideshow using ActionScript 2.0 and PHP/MySQL. The reason for this, aside from update purposes, is that the slideshow will eventually display over 200 images. Thus, to save loading time and bandwidth, I decided to use PHP to pull ten images from an SQL database, formatting the output in XML. The slideshow itself works fine. Unfortunately, there are a couple of issues I need to address; my ActionScript is extremely rusty, so much of my work's patchy.

The code's displayed below:
import mx.transitions.Tween;
import mx.transitions.easing.*;
var myShowXML = new XML();
myShowXML.ignoreWhite = true;
myShowXML.load("getData.php");
[Code] .....

The code in red is my main focus. It's the loop which loads all images as movie clips using the XML information from an array. The loop loads all of the images, making them transparent before the presentation begins. What I would like to do instead, to save loading time, is to load the next image while the current one is displaying. The function "moveSlide" controls the transition of the images, so I'd imaging it'd be best to plade it in there.

There's already an incremental variable being used, with _root.target_mc, for removing transparency from the current slide. The code in blue is also nagging me quite severely. I retrieve the next chain of slides by simply contacting the PHP script again. The only way I could think of doing that was to refresh the slideshow (this is done COMPLETELY in ActionScript, with nothing on the stage). Unfortunately, I could only work out how to reload the whole video.
