Flickr have, this week, introduced a geotagging facility, which basically means you can tag your photos by 'place' and browse other people's using a worldwide map.
There's a whole range of ways to use the tool (there's a video tutorial here if you want a quick introduction) and it's all done with the drag-and-dropiness you would expect from Flickr.
So why are we talking about it? Well, for a start you can now browse London 'photographically' which is pretty cool.
The image above is what happens when you look at London for photos tagged with 'Londonist'. While below is what happens when you look for the 'banksy' tag.
And while we're talking about photos we should remind everyone to tag your Londony images with 'Londonist' so they show up in our contribute section. We have such great stuff in our Flickr pool, it would be brilliant to see some of it appearing in our sidebar.
