History
=======
03-July-2006 v0.6 merged the 2 smuk gm scripts into a single script, and also fixed the geotagger code so it no longer needs to rely on my server
16-Sept-2006 v0.7 updated script to use Flickr's GeoAPI calls
20-May-2008  v0.8 fixed script, so it works again with latest version of GM + FF
11-Mar-2009  v0.9 fixed script to work with site redesign, batch tagging will come back in the next version
