Sharing photos via Flickr is an awesome way to archive and share photos, I’ve been using the service almost since Day 1. The now free service provides a great way to easily upload photos over mobile while it is also to have a backup of your photos hosted in the cloud. Flickr makes it a little tricky to locate your feed, however, it really is there!
Go to your Photostream, then click “More” (far right), then click “Edit” first option. Scroll to the bottom of the page and you should see links to your data feeds displayed, along with the familiar orange RSS icon. Of particular interest, the feeds are available as GeoRSS (geofeed) and KML. These feeds will enable you to visualize your geotagged photos within any map service that supports these data formats.
