    input type="button" replace with image?

    I want to have my own images as buttons so as not to use native UI on a basic html website.

    I thought this would be an easy bit, but it seems more difficult. Can anyone assist?

    The following code is working perfectly, but when I try to change the input type to a button, or insert an <img> it doesnt seem to work. Any suggestions?

    here is my Javascript in the head code:
    Code:
    <script type="text/javascript">
    
    
    var images = new Array(2);
    images[0] = "url('images/slide1.jpg')";
    images[1] = "url('images/slide2.jpg')";
    images[2] = "url('images/slide3.jpg')";
    
    var i = 0;
    
    function slideShowForward(){
            if(i==2){
                i = 0;
                document.getElementById("images").style.backgroundImage = images[i];
            }
            else{
                i++;
                document.getElementById("images").style.backgroundImage = images[i];
            }
    }
    function slideShowBack(){
            if(i==0){
                i=2;
                document.getElementById("images").style.backgroundImage = images[i];
            }
            else{
                i--;
                document.getElementById("images").style.backgroundImage = images[i];
            }
    }
    
    </script>

    HTML

    Code:
    <div id="images">
    
    <div id="form">
    <form name="buttons" action="">
    
        <input type="image" name="previous" src="images/prev.png" onClick="slideShowBack()" width="39" height="34"/>
        <input type="image" name="next" src="images/next.png" onClick="slideShowForward()" width="39" height="34"/>
        
        
    </form>
    </div> <!--form-->
    
    </div><!--images-->
    any help is always appreciated. Thanks so much!

    http://jsfiddle.net/uyLA4/4/

    That fiddle uses an image as a button.

    Not sure if this helps with your problem, but here is a neat method I was shown to rotate images without using an index variable:

    Code:
    var images = [
    	'images/slide1.jpg',
    	'images/slide2.jpg',
    	'images/slide3.jpg'
    ];
    
    function slideShowForward()
    {
    	images.push(images.shift());
    	document.getElementById('images').style.backgroundImage = 'url(' + images[0] + ')';
    }
    
    function slideShowBack()
    {
    	images.unshift(images.pop());
    	document.getElementById('images').style.backgroundImage = 'url(' + images[0] + ')';
    }
    Code:
    <div id="images" style="border: 1px solid black; height: 300px;">
    	<div id="form">
    	    <img src="images/prev.png" onclick="slideShowBack();" style="width: 39px; height: 34px;" />
    	    <img src="images/next.png" onclick="slideShowForward();" style="width: 39px; height: 34px;" />
    	</div><!--form-->
    </div><!--images-->
    This code has been tested.

    Bionoid,

    That worked perfectly, I thought for some reason I was stuck to using 'input type button'.

    Big thanks!

    You had
    HTML Code:
    <img
    You should have had:
    HTML Code:
    <img scr="URL" or "images/imagename.jpeg"
