TwitPic is a free web service that lets you attach a photo web link to a Twitter tweet. Here’s how you do it, head over to TwitPic and sign-in with your normal Twitter account name and password. Then, click on Settings and add the special email address it shows you to your cameraphone’s email contacts list. The address is in the form of: twitterusername.secretstuff@twitpic.com. If you send a photo to this email address, the email subject line will become your tweet text and a weblink to your photo will appear beside this text. Anyone who clicks on your TwitPic photo link will be able to see your photo.
