How to reorgnize xml thumbnail ? right 2 left

this is probably very simple but i just can’t work it out…
i took this script from one of the forum members, it works great and i was able to adjust many things (as space, scale and so on).

the thumbnails are 3 columns and 5 rows but the start from left to right which does not fit my design…how can i turn thing around ?

also can i fix the spacing separately for the columns and the rows ? because here it is fixed for both…

here is the script:

function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
image = [];
description = [];
thumbnails = [];
_global.total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
description* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;
thumbnails* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue;
thumbnailer(i);
}
firstImage();
} else {
trace(“file not loaded!”);
}
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad =loadXML;
xmlData.load(“images.xml”);

/////////Load First Image Function///////////////////////////////////////////////

function firstImage() {
if (loaded == filesize) {
picture._alpha = 0;
picture.loadMovie(image[0], 1);
desc_txt.text = description[0];
}
}

/////////Image Preloader Function//////////////////////////////////////////////////////

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;
}
}
};

//////////Load clicked thumbnail Image Function////////////////////////////////////////////////

function callImage() {
if (loaded == filesize) {
picture._alpha = 0;
picture.loadMovie(image[p], 1);
desc_txt.text = description[p];
}
}

//////////Thumbnail maker///////////////////////////////

function thumbnailer(k){
loaded_counter=0;
total_thumbs = _global.total;
var container = thumbnail_mc.createEmptyMovieClip(“th”+k,thumbnail_mc.getNextHighestDepth());
container._visible=false;
container._alpha=0;
var image = container.createEmptyMovieClip(“img”, container.getNextHighestDepth());
tlistener = new Object();
tlistener.onLoadInit = function(target_mc) {
target_mc.pictureValue = k;
target_mc.onRelease = function() {
p = this.pictureValue;
callImage();
};
target_mc.onRollOver = function() {
this._alpha = 50;
};
target_mc.onRollOut = function() {
this._alpha = 100;
};
loaded_counter++;
counting_txt = loaded_counter;
if(loaded_counter==total_thumbs){
grid_maker_01();
}
};
image_mcl = new MovieClipLoader();
image_mcl.addListener(tlistener);
image_mcl.loadClip(thumbnails[k], “thumbnail_mc.th”+k+".img");
}
