HELP ME!!! need to change horizontal thumbnails to vertical

[grooverider123]

Hey I just took a tutorial on how to make a thumbnail slideshow and its almost exactly what I need for my website but the thumbnails are horizontal and I need them vertical. The tutorial is here: http://www.kirupa.com/developer/mx2004/thumbnails.htm

He even mentions in the begining you can show them in a grid but doesnt explain how. HELP HELP. Im freaking out as I have a deadline. I have attached the code and the flash file which works horizontally but not vertically.

I tried changing the x values to y but that just didn't show any images at all. Can anyone please please pllllleeeease help me. I've been working on this for nearly a month and not moving forward.

Here is the code for the thumbnails. it pulls from an xml file.
thumbnails = [];
thumbnails[i] = xmlNode.childNodes[i].childNodes[2].firstChild.nodeValue;
thumbnails_fn(i);
function thumbNailScroller() {

// thumbnail code!
this.createEmptyMovieClip("tscroller", 1000);
scroll_speed = 10;
tscroller.onEnterFrame = function() {

if ((_root._ymouse>=thumbnail_mc._y) && (_root._ymouse<=thumbnail_mc._y+thumbnail_mc._heig ht)) {

if ((_root._xmouse>=(hit_right._x-40)) && (thumbnail_mc.hitTest(hit_right))) {

thumbnail_mc._x -= scroll_speed;

} else if ((_root._xmouse<=40) && (thumbnail_mc.hitTest(hit_left))) {

thumbnail_mc._x += scroll_speed;

}

} else {

delete tscroller.onEnterFrame;

}

};

}

function thumbnails_fn(k) {

thumbnail_mc.createEmptyMovieClip("t"+k, thumbnail_mc.getNextHighestDepth());
tlistener = new Object();
tlistener.onLoadInit = function(target_mc) {

target_mc._x = hit_left._x+(eval("thumbnail_mc.t"+k)._width+5)*k;
target_mc.pictureValue = k;
target_mc.onRelease = function() {

p = this.pictureValue-1;
nextImage();

};
target_mc.onRollOver = function() {

this._alpha = 50;
thumbNailScroller();

};
target_mc.onRollOut = function() {

this._alpha = 100;

};

};
image_mcl = new MovieClipLoader();
image_mcl.addListener(tlistener);
image_mcl.loadClip(thumbnails[k], "thumbnail_mc.t"+k);

}
