Need flash slideshow to play in a smaller window rather than the entire stage

I have a flash file that I got online that does almost all of what I want with a couple of exceptions:

It plays the images on the entire stage, and I want them to play in a smaller part of the stage.
It has an infobox with a countdown and mask that I would like to remove

What I want is a bigger stage that I can put a static photo in, annd have the slideshow play on a small part of the whole stage. You can see the effect that I am going for at www.lafayettekiwanis.org/scoreboard.html where I want the images of our advertisers' logo playing in the white rectangle on the screen to simulate what they looked like at the event.

The actionscript code that came with it is:

	import flash.display.Sprite;

If you need to see the php file as well that grabs the imnages automatically, it is here:

?php
	$extArray = array("jpg", "JPG", "jpeg", "JPEG", "gif", "png", "bmp", "swf");
	$dir = "images";
	
	
	header("Content-Type: application/xml; charset=UTF-8");
	
	print "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n\n";
	print "<slideshow>";
	
	if ($handle = opendir($dir)) {
		while (false !== ($file = readdir($handle))) {
			$ext = substr($file, strlen($file)-3);
			if (in_array($ext, $extArray)) {
				print "<slide file='$dir/$file' />\n\n";
			}
		}
		closedir($handle);
	}
	
	print "</slideshow>";
?>

And here is the flash file.

Nice to get generated XML

Is not bad script but I don't know why author removing and adding images over and over

I changed script little bit and add your requirements

now you can control image position and size using rect variable

private var rect:Rectangle = new Rectangle(10, 5, 400, 300);

where x - 10, y - 5, width - 400, height - 300

package  
{
	//imports
	import flash.geom.Rectangle;

	import flash.display.Stage;
	import flash.display.StageScaleMode;

Very cool. I was able to see my images the size that I specified in the .as file, but no matter what I put as the first 2 rectangle variables (which I guess is the x, y position), the images seem to play close to the upper left hand corner...

How to switch location I described in the thread but I have one mistake with calculation of size let me fix.

And to move you image you can use a rect like this

rect = new Rectangle(300, 210, 225, 154);

private function imageLoaded(event:Event) : void
{
var _loc_2:* = _imageIndex % 2 == 0 ? (_image) : (_prevImage);
_loc_2.alpha = 1;
var _loc_3:* = _imageIndex % 2 != 0 ? (_image) : (_prevImage);
Tweener.addTween(_loc_3, {alpha:0, time:3});
_loc_2.width = rect.width;
_loc_2.height = rect.height;

So would the new ActionScript file look like this ?

package  
{
	//imports
