Please help - MClip on top of other MClips

Hi Everyone

I only know very little actionscripting. I’m trying to design a photography portfolio website. I have thumbnails of photos nicely laid out on screen. When I mouse over or press on each thumbnail, I want the photo to get bigger. And when I mouse out or press on a button, I want the photo to go back to its original position.

My problem is I don’t know the actionscript that makes the MClip go over the other MClips when the MClip is played. Please see attached sample.

Sorry, I have been using the search tool of kirupa.com for hours and I have had no luck in finding a solution.

Please HELP.

This is my first post. Thanks Kirupa!
