Hi Douglas,

I’m not sure why that would be the case as it has worked for me. Perhaps a clue 
it that my code only handles the 4 common cases. Could your picture be one of 
the other four cases? Not sure. I can give you the site I found that helped me 
understand this (to the small degree that I understand it!):



Good luck.

Cannon,

I tried your code on the supplied image and had to swap the values for 6 & 8 
as, after rotation, the image was upside down.

So
 : ($lOrientation=8)  //Left 90˚, so need to rotate right 90˚
  $gPicture:=Photo_Rotate ($gPicture;90)

   : ($lOrientation=6)  //Right 90˚, so need to rotate 270˚
  $gPicture:=Photo_Rotate ($gPicture;270)

Became
 : ($lOrientation=6)  //Left 90˚, so need to rotate right 90˚
  $gPicture:=Photo_Rotate ($gPicture;90)

   : ($lOrientation=8)  //Right 90˚, so need to rotate 270˚
  $gPicture:=Photo_Rotate ($gPicture;270)

I expect your code is right so does that mean the camera was inverted 
originally to create my odd results?

Regards,  Dougie
