After installing your plugin I still see user avatars in /wp-admin/users.php that come directly from https://secure.gravatar.com/avatar/…
WordPress 5.9.3, theme: Enfold 4.9.2.3
]]>Hello,
I noticed that on Retina displays and when zooming into the browser above a certain size, Gravatar is reloaded again.
This is because the img tag also contains a srcset attribute in which the URL is not rewritten.
The problem is actually quite simple to solve.
Following code part:
public function filter_get_avatar( $img ) {
// Perform a simple strpos() search to determine if there's a need to perform the more expensive regex search and replace. If a site has a lot of non-Gravatar avatars we don't want to bog it down by performing the regex for every single avatar.
if ( ! strpos( $img, 'gravatar.com' ) === false ) {
// Regex search for src='*gravatar.com*' or src="*gravatar.com*" (case insensitive) and replace with URL for locally stored image.
$img = preg_replace( '/src=[\'"].+?gravatar\.com.+?[\'"]/i', 'src="' . plugin_dir_url( __FILE__ ) . 'mystery.jpg"', $img );
}
return $img;
}Needs to be extended by one line to look like this:
public function filter_get_avatar( $img ) {
// Perform a simple strpos() search to determine if there's a need to perform the more expensive regex search and replace. If a site has a lot of non-Gravatar avatars we don't want to bog it down by performing the regex for every single avatar.
if ( ! strpos( $img, 'gravatar.com' ) === false ) {
// Regex search for src='*gravatar.com*' or src="*gravatar.com*" (case insensitive) and replace with URL for locally stored image.
$img = preg_replace( '/src=[\'"].+?gravatar\.com.+?[\'"]/i', 'src="' . plugin_dir_url( __FILE__ ) . 'mystery.jpg"', $img );
$img = preg_replace( '/srcset=[\'"].+?gravatar\.com.+?[\'"]/i', 'srcset="' . plugin_dir_url( __FILE__ ) . 'mystery.jpg 2x"', $img );
}
return $img;
}Would be great if this could possibly be included in a new version.
Otherwise, I have it with me first manually inserted!
Maybe it would also make sense to provide the “mystery.jpg” in two different sizes, e.g. 26×26 and 52×52 pixels and to embed it accordingly!
Greetings Sascha
