(CS3 AS2) Preloading all images in XML

programming flash
1

Hi eveyone,

I’ve adapted a tutorial from here (xml photogallery) but I really need some help preloading all the images listed in my xml.

I’ve searched around and seem some other examples but nothing that I
really can apply and to be honest, with some of them I got completely
lost! (I’m obviously a designer rather than coder)

Any help would be hugely appreciated.


//IMAGES

function loadXML(loaded) {
    if (loaded) {
        xmlNode = this.firstChild;
        image = [];
        caption = [];
        total = xmlNode.childNodes.length;
        for (i=0; i<total; i++) {
            image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
            caption* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;
        }
        firstImage();
    } else {
        content = "file not loaded!";
    }
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("../xmlfile.php");
