Loading jpg into parent

programming flash

[LEFT]I’m trying to tell a button in a MC to load a jpg into a empty container in the parent
here is my code


    var myMCL:MovieClipLoader = new MovieClipLoader();
    var myListener:Object = new Object();
    myMCL.addListener(myListener);
    myListener.onLoadProgress = function(target_mc:MovieClip, bytesLoaded:Number, bytesTotal:Number) {
        var loaded:Number = Math.round((bytesLoaded/bytesTotal)*100);
        progressBar.gotoAndStop(loaded);
    };
    myListener.onLoadInit = function(target_mc:MovieClip) {
        progressBar._visible = false;
    };
    myListener.onLoadStart = function(target_mc:MovieClip) {
        progressBar._visible = true;
    };
    _parent.myMCL.loadClip("image.jpg", "main_container");
};

The main_container is on the parent but nothing appears there.
Any help would be grrrrreat!
Thanks.
