Down to earth: Geotagging photos

Even the most basic digital cameras can store a lot of useful information about photos in the EXIF format, including exposure time, aperture settings, focal length, and metering mode. The EXIF metadata can also contain the photo's geographical coordinates, which provide the exact position of where the photo was taken, but only few cameras on the market support this feature.

However, you can add geographical information to your photos (i.e., geotag them) even if you don't have a fancy camera or GPS receiver using the Geotag tool. This nifty utility allows you to quickly geotag multiple photos in one go and do some other interesting things with them.
