Twitter is now letting you add a header photo to your profile — it's a lovely new feature that seems like it draws a little inspiration from the large banner photo you get with Facebook Timeline.
All three Twitter mobile apps—iPhone, iPad, and Android—support the header photo. All three apps have been updated. iPhone and Android now include something called a photo stream, so if you just want to swipe through someone's pictures, you can click through. Twitter for iPad is new too—now it has in-line expansion for photos and videos. These updates feel a little similar to those other Twitter clients you know and love, but considering the way Twitter has been treating those third-parties, it's no surprise they're updating their own apps with these things.
