====== Mac PDF Preview : How to insert a Signature image to a PDF ======

Mandeswori  and Ujwal have found this difficult. Finally Mandeswori has found a solution and we have documented it here :

  * Use Mac Preview to view your PDF.
  * Have a signature image open as well.
  * Now Simply copying and pasting to the PDF may not work... So follow the steps below.
  * Press Command+C to copy the image. 
  * Now, bear with us: This may seem strange, but it works. Press Command+V to paste the image, and the new copy of your image will cover the original image.
  * Press Command+C to re-copy the top image
  * Now paste on to the PDF file.
