i’ve been trying out the files in kirupa’s xml photo slideshow tutorial.
please try the action script below, where i’ve disabled all alpha managment and disabled the display of the preloader.
- why is there a blanking out between display of images?
- is this a by-product of using loadMovie?
- how does one get a clean cut from one image to the next?
my intention is to have the preloader show up on top of the currently viewed image and after the next image is loaded, hide the preloader and cut to the new image.
original fla file from tutorial:

modified action script:
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");
