need help adding thumbnails and scroll buttons

[anfetienne]

ive been through a tutorial on using array for a gallery and wrote the following code.

i need to include thumbnails with left and right buttons on each side to scroll through the thumbnails

MY CODE

#include "64516994.txt"
 
this.fadeSpeed = 20;
this.pIndex = 0;
 
loadMovie(this.locVar[0], _root.photo);
MovieClip.prototype.changePhoto = function(d) {
    // make sure pIndex falls within pArray.length
    this.pIndex = (this.pIndex+d)%this.locVar.length;
    if (this.pIndex<0) {
        this.pIndex += this.locVar.length;
    }
    this.onEnterFrame = fadeOut;
};
MovieClip.prototype.fadeOut = function() {
    if (this.photo._alpha>this.fadeSpeed) {
        this.photo._alpha -= this.fadeSpeed;
    } else {
        this.loadPhoto();
    }
};
MovieClip.prototype.loadPhoto = function() {
 
    var p = _root.photo;
 
    p._alpha = 0;
    p.loadMovie(this.locVar[this.pIndex]);
    this.onEnterFrame = loadMeter;
};
MovieClip.prototype.loadMeter = function() {
    var i, l, t;
    l = this.photo.getBytesLoaded();
    t = this.photo.getBytesTotal();
    if (t>0 && t == l) {
        this.onEnterFrame = fadeIn;
    } else {
        trace(l/t);
    }
};
MovieClip.prototype.fadeIn = function() {
    if (this.photo._alpha<100-this.fadeSpeed) {
        this.photo._alpha += this.fadeSpeed;
    } else {
        this.photo._alpha = 100;
        this.onEnterFrame = null;
    }
};
// Actions -----------------------------------------
// these aren't necessary, just an example implementation
this.onKeyDown = function() {
    if (Key.getCode() == Key.LEFT) {
        this.changePhoto(-1);
    } else if (Key.getCode() == Key.RIGHT) {
        this.changePhoto(1);
    }
};
Key.addListener(this);
 

i have attached the fla that i would like my gallery to be similar to....if there are tutorials that can help please do tell.
