Topic: Would like first image to load only when promted

Hi, I would like to know if anyone has found a way to stop the first main image from loading but still have the thumbnails appear.

I would like to have a gallery on each page of my website but just display  HTML content and the thumbnails until the user clicks a thumbnail, at which point the main image would load.

I am guessing that part of the action script can be altered so that the movie that contains the main image doesn't run automatically but starts playing when a thumbnail is clicked?

Any help greatly appreciated!
