Pegman has been given a big promotion in his role of guide on Google Maps. Now, as well as showing you where Street View is available, Pegman will tell you where you can view user contributed photographs.
When you drag pegman over Google Maps blue dots will appear on the map where user contributed photographs are available. You can still tell where Street View is working because Street View availability is shown with blue lines.
If you drop Pegman on a blue dot you will then be able to view the photogrpahs at this location with the Google Maps photo browser.
