macromedia flash sitedesign: Basically what i want to do is make a background scroll with images...im pretty
sure i can use motion tweening to get this done. My major question is, how do i
make the scrolling seamless. How do I make it dow when the last photo ends,
theres no jump in the animation?

try this tutorial. http://www.cwd.dk/article.asp?articleid=122
However they use scrolling buttons. All you have to do is substitute the
buttons for images and adjust the Actionscript to suit your needs
