SCORM

I need to customize the popup that loads our Captivate presentation. All i want to do is set the size of the popup (972x648) and load a header panel bg or masthead at the top of the popup window. I'm looking at player.php to set the size of the popup, but I cannot find where I need to place my code to load my header bg into that popup window. I'm sure the content for the popup is loaded from the zip archive in the database, but it has to be formatted from somewhere. Anybody have an idea as to where I might investigate this issue. Any thoughts would be greatly appreciated. thanks.
