Twitter has announced a few new features for its iPhone app today. Users with the latest update to the Twitter for iPhone app will soon see the ability to select up to four photos at a time to upload when composing a tweet. These photos will be displayed as a collage on the tweet’s detail screen.
Along with the multi-photo support, users are also now able to tag other people in their photos. A new “who’s in these photos?” button allows you to add the username of other people in the picture. Photo tags won’t take up any characters in the body of the tweet, so the full character count will be available for composing a message.
