Manual background div slideshow

I need to make a css background image fade slideshow. For several reasons, i cannot have a physical div in my html. It's the body with a class called -home- that has a current background. There will be开发者_开发知识库 4 pictures for the slideshow, no more, no less, so that doesn't have to dynamic.

I already have the following jquery:

<script type="text/javascript">
$(document).ready(function() {
    var original_image = '#000000 url(images/bg_home.jpg) top center no-repeat';
    var second_image = '#000000 url(images/bg_home2.jpg) top center no-repeat';
    var third_image = '#000000 url(images/bg_home3.jpg) top center no-repeat';
    var fourth_image = '#000000 url(images/bg_home4.jpg) top center no-repeat';

    $('.home').click(function() {
        $(this).css('background', second_image);
    });
});
</script>

So, as you see this is a very simple script that only works if i click the general -home- div. Can anyone help me with transforming this into a simple fade slideshow without any click? It should just start executing the fade slideshow onload.

Thank you very much!

Suggestion:

$(function(){
   var images = [
       'bg_home.jpg',
       'bg_home2.jpg',
       'bg_home3.jpg',
       'bg_home4.jpg' 
   ],
   loop = 0,
   $home = $('.home');

   (function fader(){
        $home
        .fadeOut('fast', function(){
            $home.css('background', '#000000 url(' + images[loop] + ') top center no-repeat');
            $home.fadeIn('fast', function(){
                 setTimeout(fader, 3000);
            });
        });

        if(loop < images.length) 
           loop++;
        else loop = 0;                
    })();         
});
