[makeitso]

Например вот так:

<script type="text/javascript">
****function openWindow(url, width, height){
 *var args = "height="+ height +",innerHeight="+ height;
 *args += ",width="+ width +",innerWidth="+ width;
 *if (window.screen){
 *****var x = (screen.availWidth - width) / 2;
 *****var y = (screen.availHeight - height) / 2;
 *****args += ",left="+ x +",screenX="+ x;
 *****args += ",top="+ y +",screenY="+ y;
 *}
 *window.open(url, "_blank", args);
****}
</script>
