A combination of JS and PHP is the way to go (if PHP is your chosen server-side language). JQuery is a good way to easily implement a sort of starring system, I once developed this for one of my sites I later removed. It was a simple thing that had onrollover events linked to 5 images. When clicked, if it was "id 4", it'd send that as the vote of the user using jQuery's .post() function to a PHP script which noted the user and recorded the vote in a MySQL database if they hadn't already voted.
