Well i need to change my banner of the website alternatively , like once user experiences
the pic1 which would be incorporated in my CSS. But the point is i want that pic to change .
when user 1st time logs in , he see pic1 as a banner and next time or for other user , he might see a different banner ex pic2 . so in a given set of pics pic1 , pic2 , pic3 as banners , the banner keeps changing .
well i am not able to think on how to proceed since the banner link is in my CSS . have no idea on how to collaborate CSS + PHP
