title: UIImageView.Image to mail attachment with MonoTouch
body: <p>I am new to MonoTouch and I am trying to send an email with an image as attachment that a user will tame from camera or pick from gallery.</p>
  
  <p>I have created the program and it runs correctly (I have an imageview controller which loads an image from uiimagepicker to imageview. Then I call <code>MFMailComposeViewController</code> but I don't know how to pass the image from imageview to <code>addAttachmentdata</code> method.</p>
  
  <p>I suppose first I have to save the image from imageview as a file but I don't know how to do it and I can't find documentation for it.</p>
