Do you need to create a simple pop up window that is centred for your site? Here is some simple JavaScript that you can in bed in your site that uses function popUp(URL) and window.open.
Change the comma-separated list of values (See below)
Add the URL for the popup
Change the Image size and location.
Put the script in your head section of your site and image location in your body area.
<script language="JavaScript"> <!-- Begin function popUp(URL) { day = new Date(); id = day.getTime(); eval("page" + id + " = window.open(URL, '" + id + "', 'toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=600,height=500,left = 327.5,top = 234.5');"); } // End --> </script>
The values on the pop up can change to suit your needs, I have turned them off for purposes of this tutorial but if you want to change them just set the =0 to =1.
