<link rel="http://schemas.google.com/contacts/2008/rel#photo" type="image/*" href="https://www.google.com/m8/feeds/photos/media/xxxx@test.com/2d4aaf09b20bb7"/>
<link rel="self" type="application/atom+xml" href="https://www.google.com/m8/feeds/contacts/xxxx@test.com/full/2d4aaf09b20bb7"/>
<link rel="edit" type="application/atom+xml" href="https://www.google.com/m8/feeds/contacts/xxxx@test.com/full/2d4aaf09b20bb7"/>
