Twitter announced today that its mobile clients on Android and iOS, as well as its web interface, now support animated GIFs. Long a mainstay of services like Tumblr, animated GIFs have seen a resurgence in recent years, but until now Twitter forced users off the website to another service like Twitpic.

iPhone and Android users will see a small “play” button on the GIF, so it won’t play automatically, but legacy users on apps like Tweetdeck, Twitter for OS X and others will link to the web before being able to play.
It’s a small improvement to a service that many use daily, but one that will be greatly appreciated when words just aren’t enough. It also highlights Twitter’s new emphasis on photos — moving or otherwise — over text.
