Google Maps recently shows you some mapplets from famous places by searching for locations. When you search for a location, you see first four small photos on the sidebar. You can pan or zoom each of them to see it on the map and get more information or you can also explore the whole area.
By scrolling down of the sidebar, you also find related videos from YouTube, popular searches and user-created maps.
Clicking on "More photos" launches you to "Panoramio from Google", where you can show your favorite places uploading your photos, organize your photos with tags and find much more.
