> Are the thumbnails used for face recognition?

Hi Andy,
Yes, the thumbnails are used for facial recognition.  The system uses the
thumbnail to extract the dimensions of the **Unknown** face.  Known (confirmed)
face thumbnails are not used because the face dimensions have already been
extracted and saved.

The face engine uses the internal thumbnail service.  I'll do some tests to see
how the thumbnail service handles a request when the thumbnail DB is missing,
or if the DB doesn't have a thumbnail for the face.

Cheers,
Mike
