Very simple HTML/JS image slider sticks on one image?

[Magic]

So yea it just sits on one image, Excuse my noobishness but i'm a learner and am confused.

<script type="text/javascript">
        <!-->
        var image1=new image()
        image1.src="ghostfacer.jpg"
        var image2=new image()
        image2.src="fokus.jpg"
        var image3=new image()
        image3.src="da.jpg"
        //-->
        </script>
        <img src= "images/ghostfacer.jpg" name="slide" width="400" height="400">
        <script type="text/javascript">
        <!--
        var step=1
        function slideit(){
        document.images.slide.src=eval("image"+step+".src")
        if(step<3)
        step++
        else
        step=1
        setTimeout("slideit()",2500)
        }
        slideit()
        //-->
        </script>
