Need to modify this code a little

I took this code from the Kirupa Tutorial “[COLOR=#003366]Photo Gallery[FONT=Verdana] Using XML and Flash”.[/FONT][/COLOR]
[COLOR=#003366][/COLOR]
[COLOR=#003366]I’d like to modify it to not include the preloader in between each image and to fade the image out as well as in. There should be no time inbetween each image either. So basically it will transition through all of the images in the xml file fading in and out. I’d like to add a simple preloader at the very start, with a loading “bar”, also.[/COLOR]

delay = 3000;
// -----------------------
function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
image = [];
description = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
description* = 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;
this.onEnterFrame = function() {
filesize = picture.getBytesTotal();
loaded = picture.getBytesLoaded();
preloader._visible = true;
if (loaded != filesize) {
} else {
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();
}
}
}

Any help would be appreciated.

Thanks.
