Non-Gravatar profile images are replaced

[edent]

I use the WebMentions plugin to get replies to my blog posts. User's images are taken from the account which replied. FAIR Avatars overwrite those custom avatars as well as Gravatar.

For example - in the left screenshot, the first two images are Gravatars, the next two are from BlueSky, and the final one is a website's profile image. The right screenshot is what I see when FAIR avatars are enabled. I understand that the Gravatars will be replaced, but should the WebMention ones as well?

The code my theme uses to get comment avatars is:

$avatar_html = get_avatar( $comment, 64, "", "", array( "extra_attr" => "itemprop=image loading=lazy" ) );

For a WebMention avatar, it returns something like:

<img 
 alt=""
 class="avatar avatar-64 photo local-avatar"
 decoding="async"
 height="64"
 itemprop="image"
 loading="lazy"
 onerror="this.onerror=null;this.src='https://shkspr.mobi/blog/wp-content/plugins/webmention/assets/img/mm.jpg';this.srcset='https://shkspr.mobi/blog/wp-content/plugins/webmention/assets/img/mm.jpg';"
 src="https://cdn.bsky.app/img/avatar/plain/did:plc:fm7crvtisfj5xwzwuxerw32o/bafkreiepjfyygouxkrp4fybh7mqoo4b5kmk6c4wwsd52yn4hbs6ungewai@jpeg"
 srcset="https://cdn.bsky.app/img/avatar/plain/did:plc:fm7crvtisfj5xwzwuxerw32o/bafkreiepjfyygouxkrp4fybh7mqoo4b5kmk6c4wwsd52yn4hbs6ungewai@jpeg 2x"
 width="64">

For a Gravatar, it is the same, but the src is src="https://shkspr.mobi/blog/wp-content/litespeed/avatar/f5eb5c3cbe6e929f18cbe191d4b95251.jpg?ver=1750834262" because I'm using LiteSpeed to cache the images.

Would it be possible to check if an avatar is a Gravatar before replacing it?

It looks like the issue is in this code:

fair-plugin/inc/avatars/namespace.php

Line 198 in 52d2758

function get_avatar_url( $id_or_email, $args ) {

It is checking the author's ID, but perhaps it could also check if a comment has a set avatar as well?

Happy to provide more details if necessary.

Running into this issue too where use of Gravatars across the website are replaced with letters.

Here's a temp fix that I used to remove the Fair hooks causing the conflicts.

Fair warning: I've not spent a lot of time looking into possible negative effects the temp fix might have on the Fair plugin exp. On a quick glance, I am not noticing any:

<?php

/**
 * Fair Plugin Management Class
 *
 * Handles modifications and customizations for the Fair Plugin
 *
 * @since 1.0.0
 */

if (!defined('ABSPATH')) {
    exit; // Exit if accessed directly
}

class GBTI_FairPM {

    private static $instance = null;

    /**
     * Get singleton instance
     */
    public static function get_instance() {
        if (null === self::$instance) {
            self::$instance = new self();
        }
        return self::$instance;
    }

    /**
     * Constructor
     */
    private function __construct() {
        $this->init_hooks();
    }

    /**
     * Initialize WordPress hooks
     */
    private function init_hooks() {
        // Remove Fair Plugin's avatar filters to restore Gravatar functionality
        add_action('init', [$this, 'remove_avatar_filters'], 15);
    }

    /**
     * Remove Fair Plugin's avatar filters
     *
     * This restores WordPress's default Gravatar functionality by removing
     * Fair Plugin's custom avatar system that replaces images with letters.
     */
    public function remove_avatar_filters() {
        // Check if Fair Plugin's avatar functions exist before trying to remove filters
        if (function_exists('FAIR\Avatars\filter_avatar')) {
            remove_filter('get_avatar', 'FAIR\Avatars\filter_avatar', 10);
        }

        if (function_exists('FAIR\Avatars\filter_avatar_url')) {
            remove_filter('get_avatar_url', 'FAIR\Avatars\filter_avatar_url', 10);
        }

    }

}

There is a preference setting in Settings > Discussions > Avatars to use Gravatar images.

[chuckadams]

There should be an option to have an allowlist of avatar services so one could block all third-party avatars unless authorized.

[MarkWieczorek]

After activating this plugin, all gravatar images are removed:

Furthermore, in the discussion settings, there are no options to use gravatar images:

Hi @MarkWieczorek can you create a new 🐞 Bug Report issue with more details about the FAIR plugin version, WordPress version, and other plugins running on the website so we can investigate the problem in isolation?

Thanks!
