That’s a tricky one. And I don’t have a solution.

It’s probably a timing issue. The hook fires before the dir is updated.
Or maybe bp_core_fetch_avatar is cached.

Which version of BP are you using?
The issue may be related to the new approach to avatar uploads using the BP_Attachments class.

The sql call isn’t returning the user ID.

Change the sql to:
$usernames = $wpdb->get_results("SELECT ID, user_nicename FROM $wpdb->users ORDER BY ID DESC LIMIT 5");

Then make this change:
$recentusers .= '<li>' . bp_core_fetch_avatar( array( 'item_id' => $username->ID, 'type' => 'full') ) . '<a href="' . bp_core_get_user_domain($username->ID) .'">' . $username->user_nicename . '</a></li>';

Previous snippet changed all avatars (user, blogs and groups) which is not what you want. Here’s a snippet which works almost correctly, but not to 100%. Give it a try anyway.

It changes the user avatar depending of an xprofile value.

(add to bp-custom.php)

function bpfr_my_new_avatar_url() {
global $bp;

	if( bp_is_user() && ! bp_get_member_user_id() ) {
        $user_id = bp_displayed_user_id();
    } else {
        $user_id = bp_get_member_user_id();
    }

	if ( is_page( 'activity' ) ) {
		$user_id = bp_get_activity_user_id();	
	}

$ranking = xprofile_get_field_data ('ranking', $user_id );

	if ($ranking == "Top 25") {		
		$url = get_stylesheet_directory_uri() .'/custom_img/25.png';
	}
	
	if ($ranking == "Top 24") {		
		$url = get_stylesheet_directory_uri() .'/custom_img/24.png';
	}
return $url;

}
add_filter( 'bp_core_default_avatar_user', 'bpfr_my_new_avatar_url' );

Create a profile field called “ranking” with 2 options (top 24 & top 25).
Create a folder in your child-theme called “custom_img” and add 2 pictures: 24.png & 25.png (250×250)
If everybody must those avatars, disallow avatar upload in BP settings.
Site default avatar stays as Mystery Man (wp default setting).

You have also to get rid of Gravatar, so you must add this to bp-custom.php
add_filter('bp_core_fetch_avatar_no_grav', '__return_true');

The thing who doesn’t work is related to X & Y are now friends. Both willhave the same avatar.

Can probably by better improved.

Try this:

function wpse_49216_my_new_avatar_url() {
global $bp;
	if( bp_is_user() && !bp_get_member_user_id() ) {
        $user_id = 'displayed: '. bp_displayed_user_id();
    } else {
        $user_id = 'get_member_user: '. bp_get_member_user_id();
    }

$gender = xprofile_get_field_data ( 'ranking', $user_id );
   if ($gender == "Top 25") {
      return 'http://hsseek2.esy.es/wp-content/uploads/2015/04/25.png';
   }
   if ($gender == "Top 24") {
      return 'http://hsseek2.esy.es/wp-content/uploads/2015/04/24.png';
   }
}
add_filter ('bp_core_fetch_avatar_url', 'wpse_49216_my_new_avatar_url');

Probably not, but see here if it helps
http://oik-plugins.eu/buddypress-a2z/oik_api/bp_core_fetch_avatar/

bp_core_fetch_avatar( array( 'item_id' => $user_id, 'type' => 'full' ) );

‘full’ will be the large size at whatever that is set to – usually 150px.

<?php $user_id = get_current_user_id(); ?>
<a href="<?php echo bp_core_get_user_domain( $user_id ); ?>"><?php echo bp_core_fetch_avatar( array( 'item_id' => $user_id ) ); ?></a>

Your request is more properly asked of the plugin creator.
You could try this:
Open birds-author-box\public\frontend.php and replace this:

           if (get_the_author_meta('image', get_query_var('author')))
            {
                $content.= '<img class="birds_box_avatar" src="' . get_the_author_meta('image', get_query_var('author')) . '">';
            }
            else
            {
                $blank = plugin_dir_url(__FILE__) . 'img/blank.png';
                $content.= '<img class="birds_box_avatar" src="' . $blank . '">';
            }

with this:

$avatar_args = array( 
   'item_id' =>  get_the_author_meta('ID', get_query_var('author')),
   'type' => 'thumb',
   'html' => false
);

$content.= '<img class="birds_box_avatar" src="' . bp_core_fetch_avatar( $avatar_args ) . '">';

@reinforcez,

the link given by @drakedoc was started over 4 years. Many solutions are given in this thread, and the last one was published a year ago.

That solution works for 1.9 and above !

/* Skip the Gravatar check when using a default BP avatar */ 	
add_filter( 'bp_core_fetch_avatar_no_grav', '__return_true' );

By the way you have also to modify the global WP setting of avatars to “mystery man” or “nothing”.

Another solution to avoid gravatars slowing down a big site (at least > 500 members), is to use a specific cache plugin like Nix Gravatar Cache. Complete list here.

Hi @tightflks

You can use get_avatar() instead of the BuddyPress function bp_core_fetch_avatar(). See: https://codex.wordpress.org/Function_Reference/get_avatar

There might actually be more things you’d need to do. For example, the bp_get_message_thread_avatar() function uses bp_core_fetch_avatar() so you would need to filter that using bp_get_message_thread_avatar etc.

Unless someone else knows of an easier way, it seems as though it’ll be a big task of going through everything. You’d also need to be comfortable with PHP.

Alternatively, you could try disabling avatars by adding this to your bp-custom.php file

define( 'BP_SHOW_AVATARS', false );

Note: I’ve not tested that, I’m just going on what I see at the beginning of the bp_core_fetch_avatar() function. i.e:

// If avatars are disabled for the root site, obey that request and bail
if ( ! buddypress()->avatar->show_avatars )
   return;

Actually scratch that last post – it’s now displaying the avatars as the WordPress avatars in the back-end but not the front end

In that case, I think we’ve just crossed that bridge hehe. i.e the next step will be to replace all instances of bp_core_fetch_avatar() in your front-end templates with get_avatar()

Humm.. not helpful then. In that case we might have to try doing it manually. Perhaps try disabling the filter which replaces the WP avatars with BP avatars. For example, add this to your theme’s functions.php file:

remove_filter( 'get_avatar', 'bp_core_fetch_avatar_filter', 10, 5 );

I think you can disable the Gravatar fallback as well with this:

add_filter( 'bp_core_fetch_avatar_no_grav', '__return_true' );

If that doesn’t work, you may need to replace all occurrences of bp_core_fetch_avatar() with get_avatar() in your templates. But cross that bridge when you come to it.

Ref: https://codex.wordpress.org/Function_Reference/get_avatar

untested:

function no_photos() { 
	global $wpdb;

	$emails = array();
	
	$ids = $wpdb->get_col( "SELECT ID FROM {$wpdb->prefix}users" );

	foreach( $ids as $id ) { 

		$avatar_check = false;
   
		if ( bp_core_fetch_avatar( array( 'item_id' => $id, 'no_grav' => true, 'html'=> false ) ) != bp_core_avatar_default() )
			$avatar_check = true; 

		if( ! $avatar_check ) { 
			$email = $wpdb->get_var( "SELECT user_email FROM {$wpdb->prefix}users WHERE ID = $id" );
			$emails[] = $email;
		}
	}
		
	$emails = implode(",", $emails);
		
	return $emails;
		
}
