Flickr Magic View is quite, er, magical
/I've been hosting my pictures on Flickr for a long time. When if first came out Flickr was genuinely revolutionary, with unlimited online storage for subscriber's pictures.
Unlimited storage is pretty much the norm these days, and Flickr has been a bit left behind by other, fancier sites. But of late they've done some rather nice things. If you've got a Flickr account (paid or free) you might want to take a look at the new Magic View option in the Camera Roll part of your site. It does a rather good job of working out the subject of your shots and then itemising them.
I'd no idea I'd taken so many pictures of birds.....
