<div id="img" style="position:absolute;; width: 100; height: 100"><a href="list.asp?unid=261"><img src="fdgg/001.gif" border="0"></a></div>
<script LANGUAGE="JavaScript">
var xPos = 20;

img.style.left= xPos;
img.style.top = yPos;
var step = 1;

var width,height,Hoffset,Woffset;
var y = 1;
var x = 1;
var interval;
img.visibility = "visible";

yPos = 0;
}
if (yPos >= (height - Hoffset))
