jquery Background Switch

Hi Guys,

Found this link with a cool jquery background switch technicque but I was wondering on how I can get it to work so that when the user selects a new background that it remembers it?? I assume cookies but I must admit I havent a clue?

Or if someone know of another way of doing this then great!
