How to make a simple auto playing slide show with javascript?

I want to make a simple slide show that automatically plays when the page is loaded. Here is my code so far:

HTML:

<div id="slideshow">
   <div>
      <img src="slide_1.png">
   </div>   
   <div>
      <img src="slide_2.png">
   </div>
   <div>
       <img src="slide_3.png">
   </div>
</div>

CSS:

#slideshow {  

    position: relative; 

    width: 900px; 

    height: 450px;  

}

#slideshow > div { 

    position: absolute; 

}

If possible, can someone please provide me with a JavaScript code that will automatically play the slide show, as well as change the slides by using a slide transition, and also have it replay infinite amount of times while the user is still of the page? Also, maybe a navigation that has numbers in the bottom right corner. Here is an example of what I am looking for: (http://www.http://www.suprafootwear.com/). The large slideshow up top is what I want, the only difference is that I want the transition to be a linear slide motion instead of the fade transition. Please maintain the 900px x 450px size. Any help is appreciated. Thank you in advance!

Try this simple javascript code to make image slider.

<head>
    <style>
        .container{
            position:relative;
            width:100%;
            height:300px;
            border-radius:5px;
            border:1px solid red;
            overflow:hidden;
        }
    </style>
</head>
<body>
<div id="imgGallary" class="container">

</div>
<script>
(function(){
        var imgLen = document.getElementById('imgGallary');
        var images = imgLen.getElementsByTagName('img');
        var counter = 1;

        if(counter <= images.length){
            setInterval(function(){
                images[0].src = images[counter].src;
                console.log(images[counter].src);
                counter++;

                if(counter === images.length){
                    counter = 1;
                }
            },4000);
        }
})();
</script>
</body>
</html>

If you want infinite repeat on load with no buttons to control it, no need for JavaScript. Use CSS keyframe animation or transition.

Take a look at KickStart http://www.99lime.com/elements/ It has exactly what you need, and some other very useful elements for quick development.

ali

$("#slideshow > div:gt(0)").hide();

setInterval(function() { $('#slideshow > div:first') .fadeOut(1000) .next() .fadeIn(1000) .end() .appendTo('#slideshow'); }, 3000);
