Question about reusable preloader tutorial (FlashMX 04)

Hi,

I tried out the tutorial [color=black]Reusable[/color][size=1][color=#003366][size=2][color=black] Preloader Using MovieClipLoader:[/color][/size][/color][/size]
http://www.kirupa.com/developer/actionscript/moviecliploader2.htm

It worked fabulously, even a newbie like me was able to pull it off. However, I was wondering if anybody had an idea about how I would get the image that is loaded to center itself horizontally. I’m making a portfolio page, and I have lots of images of various sizes. As it is now, all images align themselves to the far left. I’m not at all familiar with Actionscript, so I don’t have the first idea how to modify the code in the tutorial.

If anyone has any suggestions, I’d greatly appreciate it.
