I want to create a website with background images that change over time with a fade in/fade out effect, but I don't want to use the existing jQuery fade in/fade out effect because with when one image faded out, a white background appeared before other image faded in. I found a plugin named Maximage that suits my request but it uses img tags while I want to work with background-image CSS (I have a good reason for doing this). Does anyone know how to do this?
Here's my HTML code:
<div id="wrapper">
//My contain here
</div>
Here's my JavaScript code so far:
//Auto change Background Image over time
$(window).load(function() {
var images = ['img/top/bg-1.jpg','img/top/bg-2.jpg','img/top/bg-3.jpg'];
var i = 0;
function changeBackground() {
$('#wrapper').fadeOut(500, function(){
$('#wrapper').css('background-image', function () {
if (i >= images.length) {
i = 0;
}
return 'url(' + images[i++] + ')';
});
$('#wrapper').fadeIn(500);
})
}
changeBackground();
setInterval(changeBackground, 3000);
});

AHH ! Finally ! I found a nice technique ! I'm using a double wrapper.
The problem in your code is a bit logical. You can't fadeOut and fadeIn at the same time a single wrapper.
So the idea is to create two wrapper and to switch between them back and forth. We have one wrapper called: "wrapper_top" that encapsulate the second wrapper called: "wrapper_bottom". And the magic was to put beside the second wrapper: your content.
Thus having the structure ready which is the following:
<div id='wrapper_top'>
<div id='content'>YOUR CONTENT</div>
<div id='wrapper_bottom'></div>
</div>
Then a bit of JS+CSS and voilà ! It will be dynamic with any amount of images !!!
Here is the implementation: http://jsbin.com/wisofeqetu/1/

<head>
<script src="http://code.jquery.com/jquery-1.10.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(window).load(function() {
var i =0;
var images = ['image2.png','image3.png','image1.png'];
var image = $('#slideit');
//Initial Background image setup
image.css('background-image', 'url(image1.png)');
//Change image at regular intervals
setInterval(function(){
image.fadeOut(1000, function () {
image.css('background-image', 'url(' + images [i++] +')');
image.fadeIn(1000);
});
if(i == images.length)
i = 0;
}, 5000);
});
</script>
</head>
<body>
<div id="slideit" style="width:700px;height:391px;">
</div>
