Slide show

So i'm trying to make my own slideshow, see above. I have the pictures showing depending what "num" equals...Well, the code's here:
CODE
<script TYPE="text/javascript">
<!--
var num = 1;
var pic = "pic.gif";

switch (num)
{
default:
document.write("<img src='pic1.gif'>");
break;

case 1:
document.write("<img src='pic1.gif'>");
break;

case 2:
document.write("<img src='pic2.gif'>");
break;

case 3:
document.write("<img src='pic3.gif'>");
break;
}

function next()
{
num ++;
alert("Done!");
}
-->
</SCRIPT>
<br>
<script TYPE="text/javascript">
<!--
document.write(num)
-->
</SCRIPT>
<br><br>
<form>
<input type="button" onclick="next()" value="Next">
</form>


(That's all in the body section, btw.)

But when I click "Next", the alert comes up, but num doesn't increase....I've tried using "num + 1" "num = num + 1" "num += 1" etc, etc, etc, but none of them work.

So my question is...How can I get it to work?
