You need a couple of fixes:

• Use a simple increment to keep track of the current image.
• typo: "images" -> "imgs"
• $("img") doesn't select anything, so the JQuery fadeto "complete" callback is never fired (I assume you meant to fade the div itself)
• you need "url('http://...')" for the "background-image" CSS property

function changeBg() {
    if (i >= imgs.length) i=0;
    $('#header').fadeTo('slow',opacity,function(){
        var val = "url('" + imgs[i++] + "')";
        console.log(val);
        $('#header').css('background-image',val).fadeTo('slow',1);
    });
}

Here is the updated demo.
