![Twitter Rules the Photo-Sharing Roost ... on Twitter [STATS]](https://helios-i.mashable.com/imagery/archives/06isQRd4Bg77ZBhoBIaNozm/hero-image.fill.size_1248x702.v1647020395.jpg)
The official Twitter app has quickly climbed to the top. According to Skylines, a social image search site, 36.1% of photos shared on Twitter come through the official image uploader. TwitPic is in second place with 30.3% and Yfrog is in third with 21.1%. Instagram is in fourth place with just 12.5%. Its low ranking is both surprising and impressive. Instagram has quickly shot up in popularity as a premiere photo app for iOS devices. This means that while 12.5% may seem low, it's coming only from people using iPhones or iPads. Not bad considering the three leaders work with web images and most major mobile carriers.
The stats are bad news for TwitPic, which previously held 45.7% of the picture-sharing market just five months previous. While some sites are already ringing the death knell for third-party photo apps, the stats shows that TwitPic and Yfrog are hanging in there. It is clear, however, that these apps will need to do something to differentiate their services from Twitter's uploader if they want to survive.
Twitter's photo-sharing win brings up the question of whether official apps and services risk killing competition and third-party innovation. This is becoming ever-more clear as Twitter ramps up its features such as URL shortening.
