<!-- Circle image -->
<div id="divCenter"><img src="images/circle.gif" name="imgCenter" width=200 height=200 border=0 alt=""></div>
<!-- Buttons -->
<div id="div0" class="clButtons"><a href="#" onclick="mclick(0); parent.focus(); return false" onmouseover="mover(0)" onmouseout="mout(0)"><img src="images/1.gif" name="img0" width=22 height=22 border=0 alt=""></a></div>
<div id="div1" class="clButtons"><a href="#" onclick="mclick(1); parent.focus(); return false" onmouseover="mover(1)" onmouseout="mout(1)"><img src="images/2.gif" name="img1" width=22 height=22 border=0 alt=""></a></div>
