Can anyone please help me with this

I have used the Kirupa xml photo gallery with thumbnails as a startingpoint for my own gallery http://www.kirupa.com/developer/mx2004/thumbnails.htm

The thing is that I need the large pictures to be right-aligned.Not left-aligned as they are in the original kirupa gallery.

Instead of having the movieclip that loads the images draw them from upper left and out, I want it to draw from upper right corner so that all images are aligned to the right.

The illustration under shows how I want things to be. (The red dot is the movieclip)

I would be soooo thankfull if anyone could help me solve this problem:)
