Doing a pro-bono site for my sister only to find her camera software is a bit unusual... it uses the flipped orientation flags

http://www.impulseadventure.com/photo/exif-orientation.html

NOTE: Values with "*" are uncommon since they represent "flipped" orientations.

Easy enough to detect to rotate, but the rotate itself causes a "flipped" image (face right when it should face left / flipped horizontally)

    $flip_image = FALSE;
    switch ($file_exif['Orientation']) {
      case 3:
        $flip_image = TRUE;
      case 2:
        $degrees = 180;
        break;

Sadly the core image toolkit don't appear to be able to handle this out of the box, so not sure on options :(

About to search core issue queue if there is a corresponding issue.
