Ho to use/call this function

programming flash
1

I feel embarassed and stupid asking this, but I post this message anyway.

I got this code from other gallery thread.
There are 3 gallery within xml : gallery 1, gallery 2, abd gallery 3.

This is the first function to call gallery list :

menuBoot = function(){
	galleryspacing = 5;
	for(var i=0;i<_global.gallery_xml.firstChild.childNodes.length;i++){
		gallerymc = gallerycontainer.attachMovie("GalleryButton","button_mc"+i,i);
		galleryloader = gallerymc.galleryloader;
		galleryaux = gallerymc.galleryaux;
		gallerymc._y = i*(20+galleryspacing);
		gallerymc.gallerybg_mc.setRGB(this._parent.gallery_btn_bg);
		gallerymc.galleryborder_mc.setRGB(this._parent.gallery_btn_border);
		gallerymc.btntext.btnname_txt.text = gallery_xml.firstChild.childNodes*.attributes.name;
		gallerymc.btntext.btnname_txt.textColor = this._parent.gallery_btn_txt;
		gallerymc.id = i;
		
		gallerymc.onRelease = function(){
			if (_global.numofthumbs != 0) {
				var nums = _global.numofthumbs;
				for (var g = 0; g < nums; g++){
					this._parent._parent.thumbmenu_mc.thumbcontainer["thumb_mc"+g].unloadMovie();
				}
			}
			_root.gallerytitle.text = gallery_xml.firstChild.childNodes[this.id].attributes.name;
			_root.caption.text = gallery_xml.firstChild.childNodes[this.id].childNodes[0].attributes.caption;
			_root.picholder_mc.loadPic(gallery_xml.firstChild.childNodes[this.id].childNodes[0].attributes.source);
			_global.delayedThumbBoot = setInterval(this._parent._parent.thumbmenu_mc.thumbBoot, 50, this.id);
		}
		gallerymc.galleryaux.onEnterFrame = function(){
			if(this._parent.galleryloader._width > 0){
				delete this.onEnterFrame;
				this._parent.onRelease = function(){
				}
			}
		}
	setGalleryRollOver();
	}
	
}

And this is is the function to display thumbnail when any of the gallery above is pressed using onRelease respectively

spacing = 10;
thumbBoot = function(calledGallery:Number){
	clearInterval(_global.delayedThumbBoot);
	var gallery_ref = _global.gallery_xml.firstChild.childNodes[calledGallery];
	_global.numofthumbs = gallery_ref.childNodes.length;
	for(var i=0;i<gallery_ref.childNodes.length;i++){
		thumbmc = thumbcontainer.attachMovie("Thumbs_MC","thumb_mc"+i,i);
		//thumbmc.brand.loadMovie(_root.thumb_brand_pic);
		thumbmc.thumbbg.setRGB(thumbnail_holder);
		thumbmc.spacer.setRGB(thumbnail_border);
		thumbloader = thumbmc.thumbloader;
		thumbaux = thumbmc.thumbaux;
		thumbmc._x = i*(75+spacing);
		thumbloader.loadMovie(gallery_ref.childNodes*.attributes.thumb);
		thumbmc.id = i;
		thumbmc.onRelease = function(){
			// attributes... Caption... Full.. Source... Thumb
			_global.downloadlink = gallery_ref.childNodes[this.id].attributes.full;
			this._parent._parent._parent._parent.caption.text = gallery_ref.childNodes[this.id].attributes.caption;
			this._parent._parent._parent._parent.picholder_mc.loadPic(gallery_ref.childNodes[this.id].attributes.source);
		}
		thumbmc.thumbaux.onEnterFrame = function(){
			if(this._parent.thumbloader._height > 0){
				delete this.onEnterFrame;
			}
		}
	setThumbRollOver();
	}
}

My question is : How to use that function so that I can load gallery 1 automatically without having to press the gallery list ?

If it’s possible I also want the first (big) image of 1st thumbnail of gallery 1 also automatically loaded.

Thanks alot for helping me out
