Slideshow of pictures not positioned properly

1

I’m using a used code of a slideshow. I figured everything except how to place the slideshow in the center of the div popup tag. This is the [URL=“http://www.gbgrafix.com/flashclips/slideshow.as”]actionscript 2.

I managed to move the pictures in the center where it says:

//slideshow parameters
slideHolder._y = 130;
slideHolder._x = 120;

on line 736

But I can’t figure the rest.
