Twitter has gone all Facebook-like, adding a User Galleries feature that brings all of your tweeted images into one place.
The service isn't official Twitter picture exclusive either; it works with Frog, TwitPic, Instagram and other imaging services too.
It shows your 100 most recent pics in a grid, or detailed view - and will grab all your images from way back on 1 January 2010. There's no video support yet though, unfortunately.
If you don't want some of your images to show up (drunken nights out come to mind) you simply have to delete the associated tweet. The gallery will also show images that you've manually retweeted, i.e. copy and pasted rather than using the retweet button.
The service is live now, although it's not yet showing up on our Twitter account.
