2. Good tutorial thank you!
   Question: I have a vewController that opens the camera and you can take a picture then it saves the image. In my secondViewController I need to load this image that was taken ans saved in my firstViewController. Can I use what you have done in the tutorial to accomplish saving the image from the camera then retrieving it in a different view?

   Thanks,
   Steve

     You can add a few lines in the next delegate method for the UIImagePickerControllerDelegate.
