TwitPic allows you to post photos on your twitter from its website or via phone. First you need to login to your twitter account to upload your photo in TwitPic. TwitPic will post the permanent photo link along with the place, tags and message that you save in TwitPic while you’re uploading your photo.
You’ll get your own url in TwitPic same as your Twitter Name (example: http://twitpic.com/photos/myochauhtun). TwitPic also has an API for developers too. You should check it out, if you’re Twitter fan. By the way, don’t forget to follow me on twitter.
