Add or change Contact Photos with Maverick

Add or change contact pictures is not working in Contacts with Maverick! Editing or Changing Contact Photos by double clicking on the photo box opens a menu with the options of: Defaults, iCloud, Faces, and Camera. However if I try and use Faces, the only thing that comes up is a message: "Find and organise photos of people in iPhoto or Aperture using Faces" No Photos load! And yes I do have Faces set up in iPhoto.
