We're proud to announce broad support of the Posterous API for image posting through the most awesome twitter clients out there. In addition to posting, many of these clients have added inline viewing of Posterous photos and media, and even voice upload (Pichirp) via iPhone!

To enable Posterous as your image host, you'll need to go into the settings for the twitter client and set Posterous as your image posting service.

Is your favorite client not here?
Posterous now supports a rich API that is also 100% compatible with TwitPic. We've added extensions that let you post music, video and files of any kind (Word, PowerPoint, etc.) so you can do even more with Posterous than any other hosting service / blog platform. Send feedback to your favorite clients telling them about our API, and let us know too.
