Please Help ME Someone!

So I used this tutuorial on kirupa about continuosly scrolling backgrounds. The link is http://www.kirupa.com/developer/flash5/imagescroll.htm I’m using flash mx for the record. I want to create moving clouds that take up the top half of my site. How can I create the same effectin the tutorial using a bigger cloud image. Please someone respond and don’t tell me to read a book or look for more tutroials b/c it’s already been done. Thanks
