Twitter might be all about words, but sometimes, as the saying goes, a picture is worth a thousand words (yep, about seven 140-word tweets). Twitpic is an easy-to-use tool for sharing photos on Twitter. Sign in using your Twitter account info, post photos from your phone or from the Twitpic site, and each of your images gets its own Twitter-friendly URL (i.e., very, very short) to make tweeting easy. Photo tags, user comments and a view counter round out the Twitpic experience. You can even view fellow twitterers’ pics on the site’s public timeline, if you choose. And because numerous third-party Twitter apps offer built-in support for Twitpic, the service can be used in plenty of handy ways to share photos on Twitter.
