open up your shop using an FTP program, browse through your files untill you find popup_image.php i belive this is in the 'includes' folder.
Copy the popup_image.php file onto your desktop so you can work on it. Open it in notepad or similar
On around line 27 you'll find the following:
<script language="javascript"><!--
function popupWindow(url) {
window.open(url,'popupWindow','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,res
izable=yes,copyhistory=no,width=100,height=100,screenX=150,screenY=150,top=150,l
eft=150')
}
//--></script>
change scrollbars=no to scrollbars=yes
