Flickr is a photo sharing webite. One of the ways of viewing the contributed images is through a geotagged RSS feed. The photographer records latitude and longitude information detailing where a photograph was taken. Where a geotagged RSS file is available this can be used in combination with Google Maps to plot the images on a map.
Paste the address for the feed into the Googler Maps Search Box, as though it were a town or post code.
Feed for an individual photographer
Feed for a Flickr Group: EOL Flickr group
Not all Flickr Groups have geotagged feeds enabled, unfortunately.
