BuddyPress.org

You shouldn’t have to edit the core files at all. I had to whip up something similar today for a client which you may find helpful.

What it does is replace the email that is used to access the gravatar with a different one. I recommend you replace the default email template with your domain, so, the gravatar will remain persistant if it’s an identicon or wavatar:

class DisableUserGravatar {



var $email_template = "member.%USER%@yourwebsite.com";



function DisableUserGravatar(){

add_filter('get_avatar', array(&$this, 'wp_avatar'), 1, 5);

add_filter( 'bp_core_fetch_avatar', array(&$this, 'bp_avatar'), 1, 3);

}



function wp_avatar( $content, $id_or_email){

if( preg_match( "/gravatar.com/", $content ) ){

if ( is_numeric($id_or_email) ) {

$id = (int) $id_or_email;

$user = get_userdata($id);

} elseif ( is_object($id_or_email) ) {

if ( !empty($id_or_email->user_id) ) {

$id = (int) $id_or_email->user_id;

$user = get_userdata($id);

} elseif ( !empty($id_or_email->comment_author_email) ) {

return $content; //Commenters not logged in don't need filtering

}

} else {

$user = get_user_by_email($id_or_email);

}

if(!$user) return $content;

$username = $user->user_login;

$email = md5( str_replace('%USER%', $username, $this->email_template) );

return preg_replace("/gravatar.com\/avatar\/(.+)\?/", "gravatar.com/avatar/{$email}?", $content);

}

return $content;

}



function bp_avatar( $content, $params ){

if( is_array($params) && $params['object'] == 'user' ){

return $this->wp_avatar($content, $params['item_id']);

}

return $content;

}



}



global $DisableUserGravatar;

$DisableUserGravatar = new DisableUserGravatar();

Create a file in wp-content/mu-plugins with the content above.

I’ll put this up on wordpress.org as a plugin.
