Top banner full size drop down to smaller size?

This is kind of a 2 part question, don’t know if this should be in the Flash forum or server-side/client-side.

First Question: I need to make a top banner for a new site, which has 4 pictures in it which will all be animated, the trick with this is I need to have it be 800x115 to show the full animation then when the pictures all move up their will be 8 or so buttons underneath the banner. Question is can I get this animation to be throughout the entire site without ever replaying that animation, without using frames? I am using php includes changing the ?id.

Second Question: If the first one doesn’t work, I need to set it up using two different tables having the top banner in one and the buttons in the other. Here’s the question, how can I do that animation from the first question with just javascripting, so the animation will not play again?

Reiterate: 1 Animation, a top banner which will be a box with 4 pictures in it will start out at full size (800x115) then the 4 pics will move up so that they will now be (800x85) and then buttons will be in the (800x30) spot.

I have seen some codes that look like they would work using cookies but I will need an explanation as to how it works if you can help me. I might have another animation in the site so I will need to make sure that some animations can play over again.
