Raj MadhuramYahoo maps + flickr = winning combination
This is way cool!. Probably the most coolest toy after Google maps. Check out the geotagging feature in flickr. It allows you to attach your photos to geographical locations (on the map). The interface is clean and excellent. I just attached a bunch of my photos to locations on the map. Check it out.
When cameras become available with GPS receivers, it should be possible to store the location in EXIF data and flickr should be able to pick that up automatically. Folks at Canon, I just got a Digital Rebel XT. Make sure you build a GPS accessory :)
