Center popup window from image map

[mjones]

Hi All,

Does anyone know an good way to do this. With all the different
monitor resolutions these days this makes sense. Right now, the
windows pop up using the left and top coordinates specified.

Here's the standard code I use that's just in a plain table.

<MAP NAME="fs-glass-slide">
<area shape="poly" alt="J2GR-47L"
coords="165,10,349,10,349,150,165,150" target="_blank"
onClick="window.open('j2gr-47L-
window.htm','','width=385,height=600,left=100,top=50')">
<area shape="poly" alt="J2GR-47L"
coords="350,10,524,10,524,150,350,150" target="_blank"
onClick="window.open('j2gr-47L-
window.htm','','width=385,height=600,left=100,top=50')">
<area shape="poly" alt="J2GR-47L"
coords="525,10,725,10,725,150,525,150" target="_blank"
onClick="window.open('j2gr-47L-
window.htm','','width=385,height=600,left=100,top=50')">
</MAP>

border="0" usemap="#fs-glass-slide" ismap NATURALSIZEFLAG="3">

Thanks,
