Here’s the bookmarklet I use for embedding Flickr CC images to blog posts. It comes from Alan Levine (@cogdog), and is a project he started on GitHub.
To understand Alan’s whys and wherefores, have a look at his documents. Alan also includes a couple of video tutorials linked off this docs.
In this class, we’re not looking at the don’t-make-me-think, ready-for-prime-time kind tools. We’re looking behind the screens, where the really interesting stuff goes on. Take the time to consider the documentation and you’ll bring a lot away with you.
