Hi! i really enjoyed the tutorial about the XML slideshow! But now i’m curious how you can load al pictures at once with a preloader instead of preloading per image! Here’s my code:

> 

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”);  
/////////////////////////////////////  
listen = new Object();  
listen.onKeyDown = function() {  
if (Key.getCode() == Key.LEFT) {  
prevImage();  
} else if (Key.getCode() == Key.RIGHT) {  
nextImage();  
}  
};  
Key.addListener(listen);  
previous\_btn.onRelease = function() {  
prevImage();  
};  
next\_btn.onRelease = function() {  
nextImage();  
};  
/////////////////////////////////////  
//84 & 182 derived from your shape dimensions  
maxh = 84-picture.\_y;  
maxw = 182-picture.\_x;  
centerx = 100;  
centery = 50;  
p = 0;  
function myfunction() {  
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;  
picture.\_xscale = picture.\_yscale=100;  
 [//trackerarray.push](https://trackerarray.push)(clip);  
var w = picture.\_width;  
var h = picture.\_height;  
if (picture.\_width\>maxw) {  
picture.\_width = maxw;  
picture.\_height = h_maxw/w;  
}  
if (picture.\_height\>maxh) {  
picture.\_height = maxh;  
picture.\_width = w\*maxh/h;  
}  
picture.\_x = centerx-picture.\_width/2;  
picture.\_y = centery-picture.\_height/2;  
if (picture.\_alpha\<100) {  
picture.\_alpha += 10;  
} else {  
delete this.onEnterFrame;  
}  
}  
};  
}  
function nextImage() {  
if (p\<(total-1)) {  
p++;  
if (loaded == filesize) {  
picture.\_alpha = 0;  
picture.loadMovie(image[p], 1);  
myfunction();  
desc\_txt.text = description[p];  
picture\_num();  
slideshow();  
}  
}  
}  
function prevImage() {  
if (p\>0) {  
p–;  
picture.\_alpha = 0;  
picture.loadMovie(image[p], 1);  
myfunction();  
desc\_txt.text = description[p];  
picture\_num();  
}  
}  
function firstImage() {  
if (loaded == filesize) {  
picture.\_alpha = 0;  
picture.loadMovie(image[0], 1);  
myfunction();  
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();  
}  
}  
}

thanks in advance everyone!
