Question

I know this sounds simple and I searched up and down the web for a script but cant find anything. I just want my backgrounds to change every 15 seconds or so automatically. (like a photo slide show but as a background.)
My style sheet is controls the bg image in the body tag.
Thanks for the help.

With setInterval, you can call an arbitrary function in, well, intervals:

(function() {
    var curImgId = 0;
    var numberOfImages = 42; // Change this to the number of background images
    window.setInterval(function() {
        $('body').css('background-image','url(/background' + curImgId + '.jpg)');
        curImgId = (curImgId + 1) % numberOfImages;
    }, 15 * 1000);
})();
