Dynamic XML picture gallery problem

hi guys, i am trying to make this xml gallery that dynamically resizes according to the picture’s width & height. the function resizer() is hardcoded with fix values. i have tried to assign it from the array like below but it works wierd, the border just keep increasing in size.

menuHolder["but"+i].onRelease = function() {

                imageLoader.loadClip(this.path,gallery.imageHolder);

                gallery.imageBorder.tween("_width",this.width,1,"easeOutExpo");
                gallery.imageBorder.tween("_height",this.height,1,"easeOutExpo");

                gallery.imageBackground.tween("_width",this.width,1,"easeOutExpo");
                gallery.imageBackground.tween("_height",this.height,1,"easeOutExpo");

                

            };

AS:

#include "lmc_tween.as"


var galleryXML:XML = new XML();
galleryXML.ignoreWhite = true;
galleryXML.onLoad = loadXML;

function loadXML(ok) {
    if (ok) {
