The MB User Avatar plugin is a specialized extension for the Meta Box framework designed to replace the default Gravatar system with locally hosted custom images. Unlike manual methods that require coding, this plugin automates the connection between a custom field and the WordPress get_avatar hook.
This is EXACTLY the same product as distributed by the developer. Sales Page
Parent Plugin: Requires the (free) core plugin to be installed and activated.
PHP Version: 7.1 or higher (PHP 8.x recommended).
WordPress Version: 6.5 or higher.
Availability: Exclusively available as part of the Meta Box Lifetime Bundle. It is not sold as a standalone individual extension.
For developers who want to fetch or manipulate the avatar data directly:
Helper Function: You can use rwmb_meta() to retrieve the image data.
License: Released under GNU GPL v2+, allowing for use in commercial client projects.
Multisite: Fully compatible with WordPress Multisite environments.
REST API: The avatar data can be exposed via the extension for use in headless WordPress or external applications.
Frontend Uploads: While it enables the field in the backend, allowing users to change avatars on the frontend usually requires the extension to create a frontend edit form.
Placeholder Support: If no custom image is uploaded, it typically falls back to the default Gravatar or the “Mystery Person” icon set in your WordPress Discussion settings.
