[F8] on enterFrame problem!! please help

[livebmx]

hello.

I have buttons on the stage that when pressed resize a border to fit the dimensions of a photograph. this works fine.

What i want is when the I test the movie in flash is for one of these images to already be visible on the stage. I know there is a simple solution to this.
but i am stumped!!
here is my code so far.

space = 10;
photo_mc._alpha = 0;

MovieClip.prototype.loadPhoto = function(photo){
photo_mc._alpha = 0;
this.loadMovie(photo);
_level0.onEnterFrame = function(){
var total = Math.round(photo_mc.getBytesTotal()/100);
var loaded = Math.round(photo_mc.getBytesLoaded()/100);

// Principally the percentage was the problem
var percentage:Number = Math.round((100/total)*loaded);
percentDisplay.text = int(percentage) + "%";
if (total != 0 && loaded>=total){
var w = photo_mc._width + space;
var h = photo_mc._height + space;
border.resize(w, h);
_level0.onEnterFrame =null;
}
}
};
MovieClip.prototype.resize = function(w, h){
var speed = 4;
this.onEnterFrame = function(){
this._width += (w - this._width)/speed;
this._height += (h - this._height)/speed;
if(Math.abs(this._width-w)<1 && Math.abs(this._height-h)<1){
this._width = w;
this._height = h;
photo_mc._x = this._x - this._width/2 + space/2;
photo_mc._y = this._y - this._height/2 + space/2;
photo_mc._alpha = 100;
this.onEnterFrame=null;
}
}
};

btn1.onRelease = function() {
photo_mc.loadPhoto("p.jpg");
};
btn2.onRelease = function() {
photo_mc.loadPhoto("p2.jpg");
};

to load p1.jpg (without button interaction) add to bottom line of your code -

photo_mc.loadPhoto("p1.jpg");
