Twitter began as a simple way to post 140 character text messages for others to follow. But the Twitterverse was not content. So sprung a whole new lexicon of @ symbols and hash marks meaningful to only the Twitterati. It wasn't long before people found ways to share their photos via Twitter, using third-party services like TwitPic and yfrog. These services are great, but for the millions of Flickr users, it was a pain to post some photos one place, and another if they wanted to share on Twitter. Or to have to grab the URL and shorten. It turned into a chore.
Today, Flickr announced that now you can tweet your Flickr photos!
There are two ways to share your Flickr photos on Twitter. For existing photos in Flickr, you first need to “Add a blog page,” authorizing Flickr to post to your Twitter account. Once you've done that, you'll see a “Blog this” button on your photo page, and you can send to Twitter from there.
If you want to upload to Flickr and post to Twitter at the same time, you can do that too! You still need to “Add a blog page” (you only need to do this once), then you'll be given a special email address. When you email a photo to that “2twitter” email address, it will both post into your Flickr account, and send a link in a Tweet for your followers. The subject line of your email will double as the title of your photo in Flickr, and the message that accompanies the URL in your tweet.
