The pre_get_avatar hook accepts parameters such as $avatar, $id_or_email, and $args. The $avatar parameter represents the avatar image tag or URL, $id_or_email is the user ID or email address, and $args are the arguments passed to the get_avatar() function.
Hook Doesn’t Work: pre_get_avatar
If the pre_get_avatar hook doesn’t work as expected, it could be due to incorrect implementation or conflicts with other plugins or themes. To troubleshoot, developers should check for syntax errors in their code and deactivate other plugins or switch to a default theme to identify any conflicts.

When using the pre_get_avatar hook, it’s important to consider the impact on performance, as modifying the avatar retrieval process can potentially increase server load. Developers should also be mindful of compatibility with other plugins and themes when customizing avatar retrieval using this hook.

function custom_avatar_size($avatar, $id_or_email, $args) {
$args[‘size’] = 100; // Set the avatar size to 100 pixels

add_filter(‘pre_get_avatar’, ‘custom_avatar_size’, 10, 3);
