Q: display an image from center_(xml load)

programming flash
1

hello kirupeans friends, I have been proving a little with an photoslide example(kirupa page).
it has helped me very much, but but with himself not to be able to change the location of the photo to show, since in the present code it shows it in the location x=0 and y=0, and its registry is located in the left superior corner.
brothers, it is possible to be changed so that all the photos are but from the center?
please help

thanks beforehand and excuses by the annoyance.


delay = 3000;
function loadXML(loaded) {
	if (loaded) {
		xmlNode = this.firstChild;
		image = [];
		total = xmlNode.childNodes.length;
		for (i=0; i<total; i++) {
			image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
}firstImage();
	} else {
		content = "file not loaded!";
	}
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("data_slide.xml");

p = 0;

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;
		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);
