Flickr has added support for geotagging photos that you upload to the website. The website to access the Flickr map is at http://flickr.com/map. To start geotagging your photos, one can go to the maps tab and start dragging and dropping photos onto the map in the correct location. In the upper right corner you can search for locations - city names, airport codes, US zipcodes and postal codes in several other countries, street addresses (US/Canada only for now, but more soon), many landmarks and points of interest worldwide, even names of neighborhoods in larger cities around the world. You drag multiple photos at once for quick mass-geotagging.
