Looped slideshow background

[FONT=System][FONT=Arial Narrow]Hi everyone, I’m still kinda new to CS4 and Flash so I apologize if this is a super dumb question (although I couldn’t find it on google or any forum); I am making a website in Flash CS4 and wanted to do a background of images that fade in and out from each other on loop and that would not get interrupted by clicking a button. Here’s an example of what I am trying to explain:


On this website you can click any button (except the Projects button), bringing up that information in a text box and the images continue to loop in the background without looking like it jumps to a different scene. Any ideas on how to make this happen in Flash?

Thanks in advance for any assistance. [/FONT]
