Change the body background image with fade effect in jquery

Question

Hey i want to fade in a new background image let´s say every 60 seconds. I´ve set the background image like this:

body {background-image: url(background.jpg)

You can use the setInterval method and switch between classes defined in your CSS which have different background-images:

setInterval(function() {
    var $body = $('body');
    if($body.hasClass('background1'))
    {
        $body.removeClass('background1');
        $body.addClass('background2');
    }
    else {        
        $body.removeClass('background2');
        $body.addClass('background1');
    }
}, 1000);

Fiddle

This example uses an interval of 1000 which is one second. You can change this value for whatever period of time you're looking for.

UPDATE

Noticed your question asked for a fade so I added a CSS3 property on body:

body
{
    transition: background 0.5s linear;
}

The fiddle has been updated.
