Positining loader clip

Question

Hello (again),
I am building a gallery for a photographer.
The setup: one large mc loader on mainstage (myLoader_mc).
Several movie clip thumbnails contained in one large movie clip.
You click on the thumbnail, large image loads into myLoader_mc. I
am using a purchased component from extend studios for my
transitions.
The problem: my jpgs are of different height and width. I
want to keep using the same movie clip to load the images
(myLoader_mc) but position the loader with different x and y
coordinates for each loaded image so that it is centered on the
stage. I am using the following script but the loader clip is stuck
in the position defined by the first thumbnail. the script is in
layer 1, frame 1 of the movie clip containing all of the thumbnail
movie clips.
th1_mc.onRelease = function(){
_parent.myLoader_mc.loadMovie("/assets/family/1b.jpg");
myLoader_mc._x = 162;
myLoader_mc._y = 5;
th2_mc.onRelease = function(){
_parent.myLoader_mc.loadMovie("/assets/family/2b.jpg");
myLoader_mc._x = 282;
myLoader_mc._y = 5;
The image loaded by thumbnail 2 is stuck in position on
thumbnail 1. Need to change this dynamically no matter which thumb
is clicked.
I had also tried creating different empty movie clips to
accomodate each different sized jpg, but I could not get the
previous loader clip to unload when another thumbnail was clicked.
The previos clip would just stay on the stage. I was using this AS:
th1_mc.onRelease = function(){
_parent.myLoader_mc.unload;
_parent.myLoader_mc.loadMovie("/assets/family/1b.jpg");
Any help is appreciated and I hope I have explained this
clearly enough. If you help me solve this, i will toast my next
drink to you.

Well, I guess we could put some closure to this thing, I
don't like loose ends. Not that i will ever remember any of it but
here's my code:
stop();
var mcl:MovieClipLoader = new MovieClipLoader(); // create a
new MovieClipLoader object
_root.loader2_mc._visible = false; // make the container MC
invisible
var lis = new Object(); // create an event listener object
lis.onLoadInit = function() {
mc._x += (Stage.width - mc._width) /2;
mc._y += (Stage.height - mc._height) /2;
_root.loader2_mc.visible = true; // make the loaded content
visible
_root.loaderfx.initEffect(); // initialize the effect
_root.loaderfx.startEffect(); // start the effect
mcl.addListener(lis); // add the listener object to the
MovieClipLoader
mcl.loadClip(img, mc); // load the image
th1_mc.onPress = function() {
loadImage('/assets/family/2b.jpg');
th2_mc.onPress = function() {
loadImage('/assets/family/4b.jpg');
Much to my amazement (ha, ha) nothing happens. this is just
from a generic test file as i deleted the original. i have a
component attached to it and what i have done is blended the code
the knuckleheads at extend studio gave me and what you have given
me, which has turned into Actionstein.
does it matter if you use "lst" or "lis"? Was wondering about
that.
Anyway, all i was asking was to load images of different
sizes into the same movie clip and have them all centered.
