Portfolio Problem

Hi,
Ive been putting together my art portfolio [ http://jake.exit-13.net/portfolio/art.html ]. If you view it though you can see that when you click on one icon the picture shows up but the next icon on release wont load the picture.

I think it might be something with my scripting im not sure.
Can some expert check it out?

Thanks

Heres the actionscript for the container__

spacing = 10;
containerc._alpha = 0;
MovieClip.prototype.loadPic = function(pic) {
_root.containerc._alpha = 0;
this.loadMovie(pic);
_root.onEnterFrame = function() {
var t = containerc.getBytesTotal(), l = containerc.getBytesLoaded();
if (t != 0 && Math.round(l/t) == 1) {
var w = containerc._width+spacing, h = containerc._height+spacing;
containerborder.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.containerc._x = this._x-this._width/2+spacing/2;
_root.containerc._y = this._y-this._height/2+spacing/2;
_root.containerc._alpha = 100;
delete this.onEnterFrame;
}
};
};

Heres the actionscript attached to the buttons___

on (release) {
containerc.loadPic(“http://fresh.urban-stylez.net/portfolio/Digital/Vectors/Nikki.jpg”);
}

on (release) {
containerc.loadPic(“http://fresh.urban-stylez.net/portfolio/Digital/Vectors/Solemn.jpg”);
}
