In the: includes/templates/custom_template/jscript/jscript_imagehover.js folder/file

I mean, looking at the source code as you probably already have, it looks like it is trying to call a window that will be the size of the image (600x600), but somewhere in the call to the new image, it drops the width for some reason/somehow.. :/
IH4 only modifies the popup_image_additional header_php.php file, not the javascript files in those folders..
