I had tried installing image handler on zen v 1.3.5 it did not work and totally took my sight down. We replaced the overwrote the files from the original zencart v 1.3.5 download. Things are back again, except for the large image popup window show the x broken link. The popup additional images window is fine and it displays fine. Is it something wrong in the modules\pages\popup_image file (looks like it is header_php.php)?
