This is complicated by the following possibility:
I have 2 contacts: Jon Phillips and Jonathan Phillips
I have 2 photos on Flickr with titles: Jon Phillips and Jonathan Phillips
I import all contacts and photos.
I edit Jonathan Phillips » Jon Phillips
I merge contacts.
Jon Phillips should now have the 2 photos.
