simple fading image swap

问题:

I'm having trouble finding a simple jquery image swap. Most the examples I've found are more complex than I need, and do things I don't want.

Objective: I have 5 images I want to fade in, slide in, or etc. I would love to fade/dissolve from one image to the next, but slide would be fine too. When the page 1st loads, I want the 1st image to show for 4 seconds...then fade to the next image, 4 seconds, then the next, etc. Infinite loop.

Currently my code is a simple image swap, not very elegant:

document.getElementById("imgMain").src = "images/yurt/sleigh.png";

What's the best and simplest way to accomplish this?

Working example on jsFiddle.

Here's the code:

HTML

<div class="fadein">
    <img src="http://farm9.staticflickr.com/8359/8450229021_9d660578b4_n.jpg">
    <img src="http://farm9.staticflickr.com/8510/8452880627_0e673b24d8_n.jpg">
    <img src="http://farm9.staticflickr.com/8108/8456552856_a843b7a5e1_n.jpg">
    <img src="http://farm9.staticflickr.com/8230/8457936603_f2c8f48691_n.jpg">
    <img src="http://farm9.staticflickr.com/8329/8447290659_02c4765928_n.jpg">
</div>

CSS

.fadein {
    position:relative;
    height:320px;
    width:320px;
}

.fadein img {
    position:absolute;
    left:0;
    top:0;
}

JavaScript

$('.fadein img:gt(0)').hide();

setInterval(function () {
    $('.fadein :first-child').fadeOut()
                             .next('img')
                             .fadeIn()
                             .end()
                             .appendTo('.fadein');
}, 4000); // 4 seconds
