Keep in mind that simply copy/pasting this code into an HTML-accepted signature won't do anything, because it is raw Javascript. Also, document.write() will write only that to the page and display nothing else.

Try this out:

<div id="pics"><img src="http://link-to-picture.jpg" /></div>

<script type="text/javascript">
function randInt(min,max)
{
     var div = (max - min) + 1
     var randNum = Math.random()
     for (var i = 0; i <= div - 1; i++)
     {
          if (randNum >= i / div && randNum < (i+1) / div)
          {return i + min}
     }
}

var i = randInt(0,3);

var pics = new Array(4);

pics[0] = "http://link-to-picture.jpg";
pics[1] = "http://link-to-picture2.jpg";
pics[2] = "http://link-to-picture3.jpg";
pics[3] = "http://link-to-picture4.jpg";


var el = document.getElementById("pics");

el.innerHTML = "<img src=\"" + pics[i] + "\" />";
</script>

EDIT: However, I really don't think that's going to work, most forums don't allow HTML in signatures and even if they do, it usually filters out Javascript.
