I have a main page in HTML, with a small flash movie on it. but I think would be more interesting if the movie wasn´t the same all the time. How do I do to play movies randomly at the main page when it is loaded?
Ps. they´re not just pictures, they are movies.
Is it possible?
Well here is a tutorial about randomly loading background images…

Why am I giving you a tutorial on randomly loading background images in Flash?
Simple… It doesn’t necessarily load random IMAGES, it loads random .SWF files… so you can make them movies and load them in randomly
