Problems with photo gallery tutorial

I got the photo gallery to work, but the photos appear in the lower right hand corner of my animation, i have been trying to figure out why for quite some time now, so now i give up and ask if anyone can tell me why, and what i need to change to get the photos to load in the center of the movie i specified. I did everything just like in the tutorial, i used the same code, except for changing the images to load. The fla is attached if needed, and here is the code i used:

this.pathToPics = “”;
this.pArray = [“scarlet1.jpg”, “scarlet2.jpg”, “scarlet3.jpg”];
this.fadeSpeed = 20;
this.pIndex = 0;
loadMovie(this.pathToPics+this.pArray[0], _root.photo);
MovieClip.prototype.changePhoto = function(d) {
// make sure pIndex falls within pArray.length
this.pIndex = (this.pIndex+d)%this.pArray.length;
if (this.pIndex<0) {
this.pIndex += this.pArray.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.pathToPics+this.pArray[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;
}
};
this.onKeyDown = function() {
if (Key.getCode() == Key.LEFT) {
this.changePhoto(-1);
} else if (Key.getCode() == Key.RIGHT) {
this.changePhoto(1);
}
};
Key.addListener(this);

Any help would be much appreciated. Thanks a lot!
