Images

Prerequisites

This image helper template takes care of providing the right path and markup for images. To make this work efficiently, specify the GitHub repository in the page header, for example:

github:
  repository: w3c/wai-repo-name
  path: content/index.md

Put images always into the /content-images/wai-repo-name/ directory (with wai-repo-name being the actual repository of the resource). This template cannot be cached.

Usage

{% include image.html
  src="picture.jpg"
  alt="alternative text"
  class="someclass"
  longdesc="/WAI/fundamentals/components/examples/"
%}

Attributes
