@gijo thank you, for the very nice plugin.
Seems that is not compatible with W3TC Page Caching function, I still see my original src entries without rewriting to Statically, and srcset includes.
However, If create custom Extension for W3TC with something like that
add_action('template_redirect', function() {
add_action('shutdown', function () {
ob_end_flush();
}, PHP_INT_MAX);
ob_start(function ($content) {
return flying_images_rewrite_html($content);
});
}, 0);
with disabling call flying_images_rewrite_html from plugin all would works.
Please, provide integration with W3TC, or just create hooks with possibility disable flying_images_rewrite_html from plugin and call in another place.
Also, do you have github for pull requests and contributing?
Thank you.
