CS3 Movie Clip Position on Stage

Hello, I’ve built a simple XML image viewer in Flash using AS2, fullscreen (noScale). You can view it here - http://www.adamwooden.com/clients/johnbb/imgviewr/

What I’m looking for is help with 2 things.

  1. I was looking for help with some code / syntax for positioning movie clips on the stage based on the width or height of the stage. For instance the small menu at the bottom, I was looking to float it off the bottom margin by say 50 pixels no matter the resolution of the screen. Another example would be imagining a menu on the left of the screen that floats 50 or so pixels from the left margin, no matter the resolution.

Any ideas on that?

  1. Is there a way to center XML dynamically loaded images inside a movie clip? If so, what is the syntax for this?

I’m a novice with flash and am experimenting for learning purposes. Any help, even a nudge in the right direction would be much appreciated.

Thanks in advance.
