Google have very recently announced that Panoramio will be closing on 4 November 2016 so this project may be quite short lived.
Read further details in the Panoramio Help Forum.
Google have stated that they plan to combine Panoramio content with the Google Maps service.
As yet there is no support for Panoramio photos within the Maps API but when this support is implemented then Photo Quiz Maps will be updated.
