BuddyPress.org

Still trying to wrap my head around taking advantage of these built in filters..

I need to change the alt-text here so that the member’s Full name is not shown. We’re using the “Usernames Only” plugin but it does not cover a few usages of our users’ names, such as in alt-text on /members avatars, as well as in pictures.php.

So first… avatars. The function in question:

function bp_member_avatar( $args = '' ) {
	echo apply_filters( 'bp_member_avatar', bp_get_member_avatar( $args ) );
}
	function bp_get_member_avatar( $args = '' ) {
		global $members_template;

		$fullname = !empty( $members_template->member->fullname ) ? $members_template->member->fullname : $members_template->member->display_name;

		$defaults = array(
			'type'   => 'thumb',
			'width'  => false,
			'height' => false,
			'class'  => 'avatar',
			'id'     => false,
			'alt'    => sprintf( __( 'Profile picture of %s', 'buddypress' ), $fullname )
		);

		$r = wp_parse_args( $args, $defaults );
		extract( $r, EXTR_SKIP );

		return apply_filters( 'bp_get_member_avatar', bp_core_fetch_avatar( array( 'item_id' => $members_template->member->id, 'type' => $type, 'alt' => $alt, 'css_id' => $id, 'class' => $class, 'width' => $width, 'height' => $height, 'email' => $members_template->member->user_email ) ) );
	}

and what I tried:
/* Hide FUll Name from member avatar */

add_filter('bp_member_avatar', 'mm_hide_name_in_alt_text');

function mm_hide_name_in_alt_text() {
  $defaults = array(
    'type'   => 'thumb',
    'width'  => false,
    'height' => false,
    'class'  => 'avatar',
    'id'     => false,
    'alt'    => 'Profile Picture' );
    
    return $defaults;
}

Looking to understand why this isn’t working?
