{
var num = Math.ceil( Math.random() * totalCount );
document.body.background = 'bgimages/'+num+'.jpg';

or you may also try it....

var colors = [
    "red", "blue", "green", "yellow", "red"
    ];
var t = setInterval(function() {
    var rand = Math.ceil(Math.random() * colors.length - 1);
    document.body.style.backgroundColor = colors[rand];
}, 30000);
var rand = Math.ceil(Math.random() * colors.length - 1);
document.body.style.backgroundColor = colors[rand];
