Just came across a pretty neat feature that Flickr launched on Monday! You can now geotag your pictures, meaning you can assign them to a physical, real-world location:
Adding location information on Flickr is done through the Organizr, under the Organize tab.
Users can search for photos by location in the Explore area. Set the map to a location (world down to street level) and type in a search query. Markers will appear on the map with photos that contain that query in the tags or description of the photo.
I just tried it out with a few of my pictures, and it seems to work pretty well. It’s all Ajax powered, so it feels pretty natural. You can check out my Flickr map here.
