Enhanced Responsive Images

Description

This plugin implements experimental enhancements for the responsive images functionality in WordPress. Currently, this includes:

  1. Improvements to the accuracy of the sizes attribute by using available layout information in the theme.
  2. Implementation of the new HTML spec for adding sizes="auto" to lazy-loaded images. See the HTML spec issue Add « auto sizes » for lazy-loaded images.

This plugin integrates with the Image Prioritizer plugin. When that plugin is active, it starts learning about which images are not in the initial viewport based on actual visitors to your site. When it knows which images are below the fold, it then adds loading=lazy to these images. This plugin then extends Image Prioritizer to also add sizes=auto to these lazy-loaded images.

There are currently no settings and no user interface for this plugin since it is designed to work without any configuration.
