Google Maps has a new photographic feature through Panoramio.com -- anyone can upload photographs of buildings, parks, streetscapes, etc., and those images will show up whenever anyone views a Google map of the location. It's very cool. I just spend half an hour adding some of my Waterbury photos.
Users can search through the map, or they can search for keywords.
To access the Google map, go to maps.google.com, search for a location, and click the "Explore the Area" link to the left.
One thing to be aware of: photographs are pinpointed to the location from which they were taken. So, for example, some photographs of the Union Station clock tower are located over by the library.
