Photos loaded from XML

Question

i found a great tutorial on how to create a photo gallery
that loads the content from an xml file. right now, the code cycles
through the pictures, and when it reaches the end it stops. also,
when you first launch the gallery (at the beginning/first picture),
the previous button does nothing. i would like to alter this to
create a loop, where there is no end. when you reach the end of the
array, the "next" button starts back at the beginning, and when
you're at the first picture in the gallery, the "previous" button
goes to the last picture. here's the code....
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();
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);
desc_txt.text = description[p];
picture_num();
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();
function picture_num() {
current_pos = p+1;
pos_txt.text = current_pos+" / "+total;
any help, ideas, suggestions, comments, or simple hello's are
much appreciated. thanks in advance! laters..........

sorry for not using the attach code feature. you think as
often as i use this site, i would have noticed that little button
before today. i have a new motto, "you learn something new
everday..... if you visit the adobe forums". ha ha.
anyweezer, so i found a solution to my problem that creates a
new question. i need to create an empty movie clip, for each
picture, each with a unique instance name. i'm thinking that the
createEmptyMovieClip would go in the for loop near the beginning of
the script. let me try this attach code thing now....
