WebCam Texture Rotation

Our "Acting Kindly" mobile game/app allows users to take selfies and share them to Facebook. The intern who wrote the WebCam.cs script didn't add functionality so the camera image rotates with the orientation of the phone. I'm only a beginner when it comes to C# and having trouble figuring out how to do this. I found one post which seems to have a script to do it...but now sure. Here's that post:

I have two basic problems:

1) Android... the script isn't rotating the camera image when the phone is rotated (to upside down from original position from when it is started) so the image both shows on the camera and posts to facebook as upside-down.

2) iOS...the image is always upside down on the phone compared to what posts. So if it looks right side up...it posts upside down and if it is upside down then it posts right side up.

Here is the script being used that causes the above behavior:

Code (CSharp):

Could I integrate the code from the post link above or is there a simple way to make the image show right side up on the camera display and save the same so the post is also right?

Thanks, Greg
