Thumbnail Buttons: Fade In, Fade Out

I tried searching for a topic similar to this. Hope I’m not repeating. I’m trying to find a way in Flash 8 to make an image fade in when its thumbnail counterpart is clicked, then fade out and get replaced by a different image when another thumbnail is clicked. The fade in-fade out part is no problem. The problem is how to get these linked to specific thumbnails/buttons using action script. I’m not versed in action script, but wouldn’t it be something like “load movie clip on release” “unload movie clip on ?”. Tried looking in tutorials, in the book, nada. I’m able to load the movie clip, but it simply keeps looping once loaded. Hopefully someone can help an action script doofus. I’ve included an image of how I’d like it work.
