Jekyll::Flickr

Liquid tag for responsive Flickr images using HTML5 srcset: {% flickr %}.

Add this line to your application's Gemfile:

$ gem 'jekyll-flickr'

And then execute:

$ bundle

Or install it yourself as:

$ gem install jekyll-flickr

Then add the following to your site's _config.yml:

plugins:
  - jekyll-flickr

💡 If you are using a Jekyll version less than 3.5.0, use the gems key instead of plugins.

You must further provide two Flickr API credentials. You can either use environment variables FLICKR_API_KEY and FLICKR_API_SECRET or the _config.yml:

flickr:
  api_key: <flickr_api_key>
  api_secret: <flickr_shared_secret>

💡 API requests are cached in .jekyll-cache/flickr for faster builds.

Use the tag as follows in your Jekyll pages, posts and collections:

{% flickr photo_id "Caption" img_attributes %}

• The photo_id is required and determines the photo from Flickr. In the URL http://alistapart.com/article/responsive-images-in-practice, the photo_id is the number in the path after the author (here also a number), i.e. 38285149681.
• The Caption is optional and must be enclosed by double quotation marks. So far, double quotation marks in captions are not supported.
• The img_attributes are any optional text that will be included in the <img> tag.

Example:

{% flickr 38285149681 "My favourite photo of the month." style="float: right;" %}

This will create the following HTML output:

<figure>
  <img src="https://farm5.staticflickr.com/4570/38285149681_f7323259a3_c.jpg" srcset="https://farm5.staticflickr.com/4570/38285149681_f7323259a3_n.jpg 320w, https://farm5.staticflickr.com/4570/38285149681_f7323259a3_z.jpg 640w, https://farm5.staticflickr.com/4570/38285149681_f7323259a3_c.jpg 800w, https://farm5.staticflickr.com/4570/38285149681_f7323259a3_b.jpg 1024w, https://farm5.staticflickr.com/4570/38285149681_2436f15109_h.jpg 1600w" sizes="100vw" style="float: right;" alt="My favourite photo of the month.">

flickr:
  api_key: <flickr_api_key>
  api_secret: <flickr_shared_secret>
  widths: [320, 640, 800, 1024, 1600]

The Flickr API provides images in a number of sizes (e.g. 75, 150, 100, 240, 320, 500, 640, 1024, 3648). The widths allows to filter for sizes to be included in the srcset attribute. The size width_legacy chosen from the supported sizes is used by browsers with no support for the srcset attribute.

The configuration option width_viewport allows to define the occupying width of the photos. It is used to set the sizes attribute. More Information

• add option to enable a link from the image to the Flickr photo page or just a larger version of the image
• allow more control on cache expiration
• allow for custom templates globally configured
• allow for templates per tag via some arguments
• block version (Liquid::Block) that allows to enclosure the caption
• use a more sophisticated RegExp to allow for captions with quotation marks
• privacy mode: download images to build to not require user requests to Flickr servers

• jekyll-flickresponsive.rb using the <picture> tag for responsive images.
