What's new

This release introduces a major new feature, Responsive Images, to further reduce LCP, especially on mobile.

This works for both HTML images and for background images in CSS files. For HTML images, a srcset attribute is added to the element containing the different sized images to load for different media sizes. For CSS images, the plugin will add additional CSS wrapped in media queries to load the different sized images at different viewport sizes.

You must optimize the images first to generate the different sizes. If images were optimized before, you may want to temporarily disable the 'Ignore optimized images' setting to facilitate a re-optimization.

Other minor improvement and bug fixes, please see CHANGELOG.

Developed and tested on up to PHP 8.3.2 and Joomla! 5.0.2
