Version 1.2.1

Release Date: July 2012
  • Added a check for the "off" returned for the $_SERVER # in IIS. Without this check, typecasting to boolean ((bool)$_SERVER #) returned true in IE whether the request was made through HTTP or HTTPS. This caused non-secure pages to try to make a secure image request.
