A picture says a thousand words. On Twitter, you only have 140 characters, so to share a picture you have to use on outside source like Twitpic. If you have a Twitter account then you automatically have a Twitpic account. All you need to do is go to Twitpic and sign in. You will then be given an email address. That email address is your road to tweeting images.
When you take an image on your phone, just select the option to email it and send it to the twitpic email address. It will be some sort of version with your username.number@twitpic.com. Whatever you want to say about the image can be put in the subject box of your email message and will come out in the tweet.
You can’t use the email address to get emals, so don’t share it with anyone.
