Popup image size. Any javascript brains out there?

[marknew]

Any javascript brains out there?
Does anyone know how to hard code the popup image size on the product info page . I know this uses three files,

two javascript files &

tpl_modules_main_product_image.php -
<script language="javascript" type="text/javascript"><!--
document.write('<?php echo '<a href="javascriptopupWindow(\\\'' . zen_href_link(FILENAME_POPUP_IMAGE, 'pID=' . $_GET['products_id']) . '\\\')">' . zen_image(IMAGES_SERVER . DIR_WS_CATALOG . $products_image_medium, addslashes($products_name)) . '<br /><span class="imgLink">' . TEXT_CLICK_TO_ENLARGE . '</span></a>'; ?>');
//--></script>

Thanks

Have you considered Image Handler 2? You can control the popup size from the admin. It's in use on both sites in my sig.
