Go to Filter ▸ Stylize ▸ Crystallize.  Play around with the settings to achieve more or less of a jagged appearance.  Click the ‘Flatten' button in the inspector palette (looks like a downward arrow).

Click on the main image layer and hit the delete key.  Deselect (⌘D).  Make your canvas slightly bigger to really see the boundary, Image ▸ Resize Canvas. 


You can also add a border around the jagged edge.  For more information read the 'Add a Border' tutorial, and follow the steps for 'Add a Border Using a Layer'.
