getLocations("london, england") does not return a great number of
Placemarks, it returns one, and the Point.coordinates of that Placemark
are the same as the .getLatLng location.
getLatLng() doesn't have its own interface to the server. It simply
makes a .getLocations() call and extracts a GLatLng from the
Point.coordinates of the first Placemark.

The elegant solution would be to use Function Closure.

I don't believe that.
Unless you supply a country bias, Scotland UK always trumps Scotland
Ohio.

Using getLocations() will also reveal the fact that many of your
requests are failing with error 620, because you're exceeding the
geocoding speed limit. Don't attempt to re-geocode each photo every time
someone opens your page. Geocode each photo once and store the
coordinates in your database.
