+
+A convenient way to manage images for a blog is to host them on Flickr.
+
+Using the Flickr API, it's possible to do lots of useful things: use Flickr to serve thumbnails, fetch the metadata associated with the image, organise your galleries by tags then show them on your blog, ...
+
+Here is a very simple example.
+
+## The flickraw gem
+
+Flickraw is a very convenient gem for accessing the flickr API, making it super-easy.
+
+Add it to your gemfile:
+
+<script src="https://gist.github.com/3156265.js?file=Gemfile"></script>
+
+<small>(And don't forget to run `bundle install`)</small>
+
+## The FlickrImage plugin
+
+**Note:** you have to define "FLICKR_KEY" and "FLICKR_SECRET" as environment variables for this script to work. <br /><small>(You can find your flickr key and secret in your Flickr interface, after having registered your app.)</small>
+
+Put this file in the 'plugins' directory:
+
+<script src="https://gist.github.com/3156265.js?file=flickr_image.rb"></script>
