Actionscript help please!

Hi everyone,
Im a long time stalker of this community and I need some assistance with actionscripting.

I want the below slideshow to load ALL the pictures at once, not just one by one. Its loading through an XML file. Here is the AS:

delay = 3500;
//-----------------------
function loadXML(loaded) {
    if (loaded) {
        xmlNode = this.firstChild;
        image = [];
        description = [];
        total = xmlNode.childNodes.length;
        for (i=0; i            image[i] = xmlNode.childNodes[i].childNodes[0].firstChild.nodeValue;
            description[i] = xmlNode.childNodes[i].childNodes[1].firstChild.nodeValue;
        }
        firstImage();
    } else {
        content = "file not loaded!";
    }
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("images.xml");
/////////////////////////////////////
p = 0;
this.onEnterFrame = function() {
    filesize = picture.getBytesTotal();
    loaded = picture.getBytesLoaded();
    preloader._visible = true;
    if (loaded != filesize) {
        preloader.preload_bar._xscale = 100*loaded/filesize;
    } else {
        preloader._visible = false;
        if (picture._alpha<100) {
            picture._alpha += 10;
        }
    }
};
function nextImage() {
    if (p<(total-1)) {
        p++;
        if (loaded == filesize) {
            picture._alpha = 0;
            picture.loadMovie(image[p], 1);
            desc_txt.text = description[p];
            picture_num();
            slideshow();
        }
    }
}
function prevImage() {
    if (p>0) {
        p--;
        picture._alpha = 0;
        picture.loadMovie(image[p], 1);
        desc_txt.text = description[p];
        picture_num();
    }
}
function firstImage() {
    if (loaded == filesize) {
        picture._alpha = 0;
        picture.loadMovie(image[0], 1);
        desc_txt.text = description[0];
        picture_num();
        slideshow();
    }
}
function picture_num() {
    current_pos = p+1;
    pos_txt.text = current_pos+" / "+total;
}
function slideshow() {
    myInterval = setInterval(pause_slideshow, delay);
    function pause_slideshow() {
        clearInterval(myInterval);
        if (p == (total-1)) {
            p = 0;
            firstImage();
        } else {
            nextImage();
        }
    }
}
