need help writing small image rotation script

[phence]

I have a column of 10 buttons, each 168 X 60 pixels.
After 300 seconds the first button should move to the bottom of the column and each of the other buttons should move up one position. This way each button has atleast five minutes in the top position.

A user should not see the rotation.
When a user views the page which ever button is at the top of the column will remain at the top of the column unless the user refreshes the page after that buttons 300 seconds is up.
When the page refreshes(if the 300 seconds has expired), the 2nd button on in the column now appears at the top and the first button appears at the bottom.

if anyone could generously write this little scriptlet, i would greatly appreciate your help!
Thank-you

Ah, I think I've got just the thing. I wrote a script that does almost exactly this as an example for my site and you're welcome to use the script for free. Have a look at the examples page on my site. It's called the Rotating Directory script but it would work perfectly using just images, infact when I originally wrote it, that's all it did 🙂 Let me know if you'd like the script.
