preloading images from xml file for ready display

Hi ,

I have a xml file from which i am loading images to view. every time the suer needs to clik on the images to load it from the xml file . Is it possible to preload the images..so if th euser clicks on the thumbnail the image will load fast?

this is the code written:

delay = 3000;
//-----------------------
function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
image = [];
th = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
image = xmlNode.childNodes.childNodes[0].firstChild.nodeValue;
th = xmlNode.childNodes.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;
loadline._alpha = 0;
this.onEnterFrame = function() {
filesize = picture.getBytesTotal();
loaded = picture.getBytesLoaded();
preloader._visible = true;
if (loaded != filesize) {
loadline._alpha = 100*loaded/filesize;
preloader.preload_bar._xscale = 100*loaded/filesize;
} else {
preloader._visible = false;
if (picture._alpha<100) {
picture._alpha += 10;
}
if (pictureth._alpha<100) {
pictureth._alpha += 10;
}
}
};
function firstImage() {
if (loaded == filesize) {
picture._alpha = 0;
picture.loadMovie(image[0], 1);
pictureth._alpha = 0;
pictureth.loadMovie(th[0], 1);
picture_num();
slideshow();
}
}
function picture_num() {
current_pos = p;
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();
}
}
}
slideshow();
