help me customize a scrolling image tutorial pls

[christylove]

hi, i'm hoping you guys can help me figure out how to customize this flash scrolling book movie i have. I found a great tutorial online and followed it and loved it. http://www.republicofcode.com/tutori.../imagegallery/

my scrolling book movie - http://bit.ly/cmbafB

in that tutorial you will notice he has the user clicking on the images and seeing the image larger. I would like each image when clicked to go to a specified url.

I don't know crap about code and want to finish my project. i would like to understand what is going on so I can figure it out next time myself.
His comments are VERY helpful, but i am still confused a bit.

for (i=1; i<=imagesNumber; i++) {
container.attachMovie("thumb"+i,"thumb"+i+"_mc",i);

when this code runs i is equal to 1.
imagesNumber is 17, so we know i is less than imagesNumber. i++ increments i, so is i now = to two? so is the container that will be created named: thumb2_mc?
what does the i (i bolded it)mean on the end of the code?

to add my urls, how do i tell this thing to attach my urls to each thumb_mc?
I did a trace on myThumb_mc and it's 17 everytime. why is that? Where in the code is it assigning each image a name and can I assign a url to it too?
sorry to be a pain. i got a lot of questions and i'm confused as heck.

import mx.transitions.Tween;
import mx.transitions.easing.*;

//Creating the Container
this.createEmptyMovieClip("container",1);


var imagesNumber:Number = 17;
for (i=1; i<=imagesNumber; i++) {
container.attachMovie("thumb"+i,"thumb"+i+"_mc",i);

//Attaching the Images and Aligning Them on Stage

myThumb_mc = container["thumb"+i+"_mc"];
myThumb_mc._x = (i-1)*myThumb_mc._width;
myThumb_mc._y = (Stage.height-myThumb_mc._height)/2
}

//Creating the Scrolling Effect - to speed up or slow down change (*5) container.onEnterFrame = function (){
this._x += Math.cos((-_root._xmouse/Stage.width)*Math.PI)*5;
if (this._x>0) {
this._x = 0;
}
if (-this._x>(this._width-Stage.width)) {
this._x = -(this._width-Stage.width);
}
};

//Assigning a Variable to Each Thumb

for (i=1; i<=imagesNumber; i++) {
container.attachMovie("thumb"+i,"thumb"+i+"_mc",i);
myThumb_mc = container["thumb"+i+"_mc"];
myThumb_mc._x = (i-1)*myThumb_mc._width;
myThumb_mc._y = (Stage.height-myThumb_mc._height)/2
myThumb_mc.largerImage = i;
}



//making the buttons clickable

myThumb_mc.onRelease = function(){
			
_root.attachMovie("image"+this.largerImage,"large_mc",2);
trace(myThumb_mc);
}
}

can't i simply add a if(myThumb_mc is = to 3 url ="http....) instead of _root.attach...
myThumb_mc.onRelease = function(){

_root.attachMovie("image"+this.largerImage,"large_ mc",2);
trace(myThumb_mc);
