Street View has been given a small makeover: while viewing Street View in Google Maps, there is a border around the Street View window that will turn blue when you hover over the "x".
But the biggest and most exciting change about Street View is a new feature called user photos.
Now, when you view popular Street Views in Barcelona, New York, New Zealand, Rome, San Francisco, Sydney, and Tokyo, a small image thumbnail will appear in the Street View's upper-right corner with the caption "User Photos".
Clicking this icon will adjust the Street View and open the first of a whole set of photos provided by Panoramio users. Panoramio, a service from Google, is a great way to share your geolocated photos. Google has reviewed many of these millions of pictures, and placed them into Street View for your enjoyment.
This new feature can be very useful for Street Views with not-so-good-looking atmosphere, like some taken on dark, cloudy days. User photos, I predict, will soon be popping up all over the Street View world. That would be fun!
