I did a similar thing recently with rotating headers. Instead of using
a date/day we just settled on using the session, so that the header
will remain stable for the life of the session - usually the time the
browser is open - but not change when moving between pages.

I just:
* did session_start() at the top of the pages
* set up MAXHEADERS as a define() constant for the maximum number of
headers
* uploaded 5 different files like header-?.jpg
* then called this function to return me the name of the current
header file:

function header_rotate() {
if (!isset($_SESSION['headername'])) {
$_SESSION['headername']='header-'.rand(1,MAXHEADERS).'.jpg';
}
return $_SESSION['headername'];
}
