When a user clicks in the "What's Happening?" box, a camera icon now appears at the bottom. The user can click it to add an image to the tweet. Twitter's photo-sharing is powered by
Photobucket, which will host all uploaded images. Photos can be up to 3 MB. Depending on their size, they may affect the amount of text, usually up to 140 characters, that the user can tweet.
The feature has already been switched on for some users and should be available to all users over the next couple of weeks. -news.brothersoft.com
