Practical with this below

<style type="text/css" media="screen">
#container{position:relative;width:120px;height:120px;}
#container div{position:absolute;width:120px;height:120px;}
#box-red{background:red;}
#box-yellow{background:yellow;display:none;}
#box-green{background:green;display:none;}
#box-maroon{background:maroon;display:none;}
</style>

Javascipt

<script type="text/javascript">
var $c =0;
function next(){
    var boxes = document.getElementsByClassName("box");
    $c +=1;
    if($c >= boxes.length) $c = 0;
    for (var $i=0;$i<boxes.length;$i++){
        boxes[$i].style.display  = "none";
    }
    boxes[$c].style.display  = "block";
    return false;
}
function prev(){
    var boxes = document.getElementsByClassName("box");
    $c -=1;
    if($c < 0) $c = (boxes.length-1);   
    for (var $i=0;$i<boxes.length;$i++){
        boxes[$i].style.display  = "none";
    }
        boxes[$c].style.display  = "block";
    return false;   
}
</script>

HTML

    <div id="container">
    <div id="box-red" class="box">DIV1</div>
    <div id="box-yellow" class="box">DIV2</div>
    <div id="box-green" class="box">DIV3</div>
    <div id="box-maroon" class="box">DIV4</div>

I think this is what you are loking for:
http://girlswhogeek.com/tutorials/2007/show-and-hide-elements-with-javascript

But you could put that in one function:

<script language="JavaScript">
function ShowHide(divId){
    if(document.getElementById(divId).style.display == 'none')
    {
        document.getElementById(divId).style.display='block';
    }
    else
    {
        document.getElementById(divId).style.display = 'none';
    }
}
</script>

function toggleImage(forwrad){
var imageConainer = document.getElementByID(Your Parent div id);

var images = imageContainer.childNodes;

var showIndex = '';
for(var i=0; i<images.length;i++){
  if(images[i].style.display == 'block'){
    images[i].style.display == 'none';
    if(forwrad){
      showIndex = 1+1;
    }
    else{
      showIndex = 1-1;
    }
  }
}
images[showIndex].style.display = true;
}

technically it's possible with pure CSS as well. with the :target pseudo class. but that would pollute your url with # tags. But you may actually want that.

Also Selectivizr is a good polyfill for old browsers
