Similar to Buzz but using Flickr as the image backend

The last part of my very simple Map API tutorial at http://toys.lerdorf.com/archives/35-GeoCool!.html. It just grabs the earthquake data from USGS and sticks it on a map.

Version 3 of the Yahoo! Maps DHTML API. You can feed it a geocoded RSS file directly now, so the above earthquake mashup becomes: http://lerdorf.com/ymap?q=http://earthquake.usgs.gov/eqcenter/recenteqsww/catalogs/eqs7day-M2.5.xml
