Geotagging your photos is a great idea. The problem is, it can be a pain in the arse to do. I do a lot of mine through Flickr and the Localize Bookmark, but it takes time and is hardly perfect. The JOBO photoGPS Geo-Data makes it a whole lot easier. See the link below for a great write up about Geotagging, the whys and hows.
