laod and grow as sub problem

[headkick]

Thought I had worked this all out but another question has popped up.

I am using the following code from Jesse to do a load and grow function for a library of photos. It works fine on the main stage, but I need this to work as a sub-menu. The grow function works as a sub, but the image is not showing up.

// Actions for buttons
btn1_btn.onRelease = function() {
    loadThenGrow("photos/02_ph_2nudes.jpg");
};
btn2_btn.onRelease = function() {
    loadThenGrow("photos/02_COL_edinburgh.jpg");
};
// LoadTheGrow function takes a target image name.
// Targets are hard-coded for the moment because I'm lazy
function loadThenGrow(img) {
    bg_square_mc._parent.holder_mc.removeMovieClip();
    bg_square_mc._parent.createEmptyMovieClip("holder_mc", 1);
    bg_square_mc._parent.holder_mc._visible = false;
    bg_square_mc._parent.holder_mc.onData = function() {
        if (this.getBytesLoaded() == this.getBytesTotal()) {
            this._visible = false;
            // Image fully loaded, grab dimensions and resize
            // background clip
            w = this._width;
            h = this._height;
            bg_square_mc.growTo(w+1, h+1, 10, _root.showHolder);
        }
    };
    bg_square_mc._parent.holder_mc.loadMovie(img);
}
function showHolder() {
    w = bg_square_mc._parent.holder_mc._width;
    h = bg_square_mc._parent.holder_mc._height;
    bg_square_mc._parent.holder_mc._x = bg_square_mc._x-w/2;
    bg_square_mc._parent.holder_mc._y = bg_square_mc._y-h/2;
    bg_square_mc._parent.holder_mc._visible = true;
    bg_square_mc._parent.holder_mc._alpha = 50;
        trace ("Image resized");
        bg_square_mc._parent.holder_mc.fadeTo(5, _root.doneHolder);
        
}

MovieClip.prototype.fadeTo = function(fadeRate, callback) {
        if ((fadeRate == undefined) or (fadeRate<=0)) {
                fadeRate = 10;
        }
        if (!this.fading) {
                this.fading = true;
                this.fadeInterval = setInterval(this, "doFadeTo", 60, fadeRate, callback);
        }
};
MovieClip.prototype.doFadeTo = function(fadeRate, callback) {
        if (this._alpha > 100) {
                
                clearInterval(this.fadeInterval);
                this.fading = false;
                if (callback) {
                        callback();
                }
        } else {
                this._alpha += fadeRate;
        }
};

This is the grow function:

// MovieClip growTo Proto v1 by Jesse Stratford
// [email][email protected][/email]
// You may use this script as you wish provded these comments remain
// Arguments:
//    w - target width
//    h - target height
//    growRate - higher = slower
//    callback -    funtion to call when growing is complete
MovieClip.prototype.growTo = function(w, h, growRate, callback) {
    // If the grow rate is undefined or invalid, set it
    if ((growRate == undefined) or (growRate<=0)) {
        growRate = 10;
    }
    // Only grow if currently not growing
    if (!this.growing) {
        this.growing = true;
        // Call doGrowTo at regular intervals (change the '60' below if you wish)
        this.growInterval = setInterval(this, "doGrowTo", 10, w, h, growRate, callback);
    } else {
        // already growing, don't start again.
        // might want to indicate some sort of error here
    }
};
MovieClip.prototype.doGrowTo = function(w, h, growRate, callback) {
    // Get the current width and heigh of the clip
    wDiff = w-this._width;
    hDiff = h-this._height;
    // Inertia resize workaround. If we're within 2 pixels, snap to size.
    if (Math.abs(wDiff)<2 && Math.abs(hDiff)<2) {
        this._width = w;
        this._height = h;
        // Stop the grow interval (save CPU)
        clearInterval(this.growInterval);
        // Reset growing variable
        this.growing = false;
        // Call function if one was passed
        if (callback) {
            callback();
        }
    } else {
        // Keep growing if we haven't reached our target size.
        this._width += wDiff/growRate;
        this._height += hDiff/growRate;
    }
};

Again everything here works fine on the main stage level (1). But it does not show the photo when used as a sub-menu. Any suggestions?

Thanks in advance.

Thought I should include this. The original script for this by Jesse is located:

http://www.actionscripts.org/showMovie.php?id=754

It contains a zipped fla to view how it works. Basically I am doing the same thing but as a sub menu with an alpha.
