Improvements for responsive images in WordPress.

== Description ==

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

1. Improvements to the accuracy of the `sizes` attribute by using layout information available in [block themes](https://wordpress.org/documentation/article/block-themes/). This enhancement is not available to classic themes.
2. Implementation of the new HTML spec for adding `sizes="auto"` to lazy-loaded images. This enhancement was [merged](https://make.wordpress.org/core/2024/10/18/auto-sizes-for-lazy-loaded-images-in-wordpress-6-7/) into WordPress 6.7.

See also the complimentary [Image Prioritizer](https://wordpress.org/plugins/image-prioritizer/) plugin which detects which images are outside the viewport, and then adds `loading=lazy` and `sizes=auto` to them.

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