Flash 8 Advanced Button Actions

1

I’m creating a header with navigation buttons that are thumbnails of larger images. When a button is moused over I would like a short transition, that spans the entire stage, followed by a display of a larger image of the thumbnail button on the left side of my stage. The transition is constant for each button but the images pertain to specific areas of my site. Basically I’d like to use this mouseover as a visual preview and when then the button is clicked the visitor is taken to that particular section of my site. Any advice on how to accomplish this and keep my file size fairly small would be greatly appreciated. Thank you.
