Google: Put Photos on a map, Picasa on Phone
Official Google Blog: Put your photos on a map, and Picasa on your phone: A new Picassa option, ‘Map My Photos’ lets you show exactly where you took your favorite snapshots.
When you share an album with friends, they can see your best photos arrayed on a map (or even Google Earth). It’s the perfect way to showcase a memorable road trip or a globe-trotting vacation.
Tip: when you create a new album, just fill in the optional ‘Place Taken’ field. You can even drag and drop individual photos directly onto a map, and use built-in Google Maps technology to pinpoint exactly where each was shot.
For a quick peek at what the results look like, check out our test gallery." Visit picasaweb.google.com/m/ on your mobile web browser to see your album.
