This may be old-school for some of you, others will appreciate this simple tip.  All you need here is a Nokia N95 or other GPS-enabled device, some geotagged photos, a flickr account, a geo-RSS feed, and a Google account (optional) - read on for this simple GeoRSS photo feed, google map tutorial

If you use a GPS-enabled cameraphone (like the Nokia N95, N82, Nokia Navigator etc...) then you can easily post your photos to flickr or other online services (use a tool like Shozu to help with this). But did you know that Flickr creates a Geo-RSS feed from your photo stream? Even better, you can simply copy and paste your Geo-RSS feed location into the google maps search bar and voila... your photos are now available via Google maps to share with others, save to your mymaps or whatever the heck you want to do. Simply look at the bottom of your flickr page, you'll see options like RSS, GeoFeed and KML - yes you can easily open your photos in Google Earth too with a flickr provided KML file!

For users of Google, if you save your custom map in your MyMaps you'll have the ability to easily share your map feeds and you can even embed them in a webpage or blog.  

Go to your flickr page, scroll to the bottomcopy the GeoRss feed url
jump back to google maps
paste the RSS feed url into the search bar and click "search maps"
click the "Link to this page" you can grab a link or embed the map into your webpage (See image below)

The link to this page provides a link back to Google Maps where you can view the photos 

Selecting the Paste html code into your webpage is simple and displayed below - this is a live Google Map pulling my geotagged photos from the GeoRSS feed via Flickr.
