Help With Slideshow Fade-in / Fade-out

After browsing through the forum, I found this great actionscript to randomly load images into a blank movieclip. This is much simpler than the script I have been using. Below is the actionscript:

rNum = random(50)+1;
_root.blankmovie.loadMovie(rNum+".jpg");
function mcPlay() {
        play();
        clearInterval(myInterval);
}
myInterval = setInterval(mcPlay, 10000);
stop();

How would I alter this script so it fades-in the random image, waits 10 seconds, fades-out the image, and then fades-in a new random image and repeats this process? I guess it would do something with alpha, but I don’t know how to do it. If you could, please re-paste this script with the changes in it because I’m not very good at writing actionscript. I’ll appreciate any help!
