<script type="text/javascript">
document.getElementById('special_panel_body').getElementsByTagName('img')[0].style.width='120px';
document.getElementById('special_panel_body').getElementsByTagName('img')[0].style.height='200px';
</script>
height : width ratio is 110 to 80
So if you want a width of 210 then the height would be:
210 * 110 / 80 = 289
