Some problems with my image resizer

programming flash
1

ok over at my site 2wodesigns
Im using the resizable border in my portfolio and for some reason, when i preview in flash it works perfectly, but online it shrinks the border and loads the image down to the right. can anyone explain what i might have done wrong in publishing or in code, thanks.

spacing = 10;
containerMC._alpha = 0;

MovieClip.prototype.loadPic = function(pic){
	_root.containerMC._alpha = 0;
	this.loadMovie(pic);
	_root.onEnterFrame = function(){
		var t = containerMC.getBytesTotal(), l = containerMC.getBytesLoaded();
		if (t != 0 && Math.round(l/t) == 1){
			var w = containerMC._width + spacing, h = containerMC._height + spacing;
			border.resizeMe(w, h);
			delete _root.onEnterFrame;
		}
	}
};
MovieClip.prototype.resizeMe = function(w, h){
	var speed = 3;
	this.onEnterFrame = function(){
		this._width += (w - this._width)/speed;
		this._height += (h - this._height)/speed;
		if( Math.abs(this._width-w)<1){
			this._width = w;
			this._height = h;
			_root.containerMC._x = this._x - this._width/2 + spacing/2;
			_root.containerMC._y = this._y - this._height/2 + spacing/2;
			_root.containerMC._alpha = 100;
			delete this.onEnterFrame;
		}
	}
};
