Hi there,
Thanks for this great plugin.
As apaunovski pointed, it would be nice to add in the upload dir the WebP images and change url in html files.
There is an easy fix that I tried :
In the plugin dir, there is a file
src/class-ss-url-extractor.php
.
Change line 57 -> 'source' => array( 'src' ),
To -> 'source' => array( 'src', 'srcset' ),
I’m not familiar with the type of SVN used for WordPress Plugins so it would be nice if the author can change that in his plugin code.
Cheers,
