Need Help Creating an Array in Flash

I have an older version of a Flash photo gallery (Flash 8/Action Script 1).  I'm using Flash CS3 to edit the source FLA file on an Windows XP Dell PC.  The gallery uses an external XML file to populate the gallery.  The original XML calls for :
       <pic>
        <image>gallery/photo01_web.jpg</image>
        <thumbnail>gallery/photo01_thumb.jpg</thumbnail>
        <caption>Insert caption here</caption>
        </pic>
I want to add a 4th node so that the user can download a hi-res version of the photo.  The XML would now be:
        <pic>
        <image>gallery/photo01_web.jpg</image>
        <thumbnail>gallery/photo01_thumb.jpg</thumbnail>
        <caption>Insert caption here</caption>
        <original>gallery/hires/photo01_hires.jpg</original>
       </pic>

The download button works on the first image, but will not work on the second, third, etc. images in the gallery.  If I go back to the first image after clicking the other images, the download for the first image no longer works.

The AS1 is below.  Can someone help me with make the array work>
function initGallery() {
	function loadXML(loaded) {
		if (loaded) {
			xmlNode = this.firstChild;
			total = xmlNode.childNodes.length;
			for (i=0; i<total; i++) {
				_root.small_image[i] = xmlNode.childNodes[i].childNodes[1].firstChild.nodeValue;
				_root.big_image[i] = xmlNode.childNodes[i].childNodes[0].firstChild.nodeValue;
				_root.description[i] = xmlNode.childNodes[i].childNodes[2].firstChild.nodeValue;
				_root.original[i] = xmlNode.childNodes[i].childNodes[3].firstChild.nodeValue;
				if (i == 0) {
					_root.loadGImage(_root.description[i],_root.big_image[i], _root.original[i]);
				}
				// end if   
				++_root.total_images;
			}// end of for
			createSmall();
			_root.downloadButton._visible = true;
		} else {
			content = "file not loaded!";
		}// end else if
	}// End of the function
	xmlData = new XML();
	xmlData.ignoreWhite = true;
	xmlData.onLoad = loadXML;
	if (_root.xml_file == undefined) {
		_root.xml_file = "images.xml";
	}
	// end if   
	xmlData.load(xml_file);
}// End of the function
function createSmall() {
	_root.smallContainer.createEmptyMovieClip("smallImageContainer",10);
	var _loc4 = 0;
	var _loc3 = 0;
	for (var _loc2 = 0; _loc2<_root.small_image.length; ++_loc2) {
		_root.smallContainer.imageContainer.attachMovie("smallImage","smallImage_"+_loc2,100+_loc2);
		m = _root.smallContainer.imageContainer["smallImage_"+_loc2];
		m._x = _loc3*50;
		m._y = 0;
		m.imageContainer.loadMovie(_root.small_image[_loc2],100);
		m.iData = Array();
		m.iData.big = _root.big_image[_loc2];
		m.iData.title = _root.description[_loc2];
		++_loc3;
	}// end of for
	_root.smallImageContainer._x = 5;
	_root.smallImageContainer._y = 0;
}// End of the function
function loadGImage(title, bigImgURL, originalURL) {
	_root.bigImage.imageContainer.loadMovie(bigImgURL,100);

	_root.bigImage.imageContainer._y = 0;
	_root.title.text = title;
	_root.downloadButton.onRelease = function() {
		getURL(originalURL, "_blank");
	};
}// End of the function
function goFullScreen() {
	Stage.displayState = "fullScreen";
}// End of the function
function exitFullScreen() {
	Stage.displayState = "normal";

	} else {
		menuObj.customItems[0].enabled = false;
		menuObj.customItems[1].enabled = true;
	}// end else if
}// End of the function
_root.description = new Array();
_root.small_image = new Array();
_root.big_image = new Array();
_root.original = new Array();
_root.total_images = 0;
initGallery();
var fullscreenCM = new ContextMenu(menuHandler);
fullscreenCM.hideBuiltInItems();
var fs = new ContextMenuItem("Go Full Screen", goFullScreen);
fullscreenCM.customItems.push(fs);
var xfs = new ContextMenuItem("Exit Full Screen", exitFullScreen);
fullscreenCM.customItems.push(xfs);
_root.menu = fullscreenCM;
downloadButton._visible = false;

Post the .fla together with the .xml. I cannot be sure what is wrong with only the code shown.

Thanks for hte help.  The EE system would not accept .FLA files for upload. I've posted them to the following location:  http://www.dfwserver.com/temp02

I found your problem, and since I do not have the photos I could not really test out properly, but I'm quite sure this code will work.

I uploaded the .fla and renamed it as .fla.txt, so you rename the .fla back to .fla.

Thank you so much, but there's a problem with opening the file.  I downloaded and renamed it, but Flash CS3 keeps giving me an "unexpected file format" error.  I think this EE upload system may have corrupted it.  Can you copy-and-paste the AS code?

As the code is really scattered here and there, yeah you originally coded it like this so I didn't change them, so it's rather difficult for me to show which code belongs where but I will try.

Anyway I think you are unable to open it because I accidentally saved it as flash cs4 format. So try the new flash file and if you still cannot, see the code snippet on how to edit your code.
