Método para trocar avatar de usuário (Jom Social)

Para trocar o avatar do usuário logado (sistema Jom Social), usar o seguinte código:

    // Atualiza o avatar do Jom Social para o usuário atualmente logado. A localização da imagem deve ser informada por $pathImagem
    public static function jsAtualizarAvatar( $pathImagem = '' ) {
 
        require_once(JPATH_SITE . '/components/com_community/helpers/image.php');
 
        $my = CFactory::getUser();
 
        $userid	= $my->id;
 
        $size = getimagesize( $pathImagem );
        $file['tmp_name'] = $pathImagem;
        $file['type'] = $size['mime'];
 
 
        $config = CFactory::getConfig();
        $uploadLimit = (double) $config->get('maxuploadsize');
        $uploadLimit = ( $uploadLimit * 1024 * 1024 );
 
        // @rule: Limit image size based on the maximum upload allowed.
        if (filesize($file['tmp_name']) > $uploadLimit && $uploadLimit != 0) {
            return false;
        }
 
        if (!CImageHelper::isValidType($file['type'])) {
            $mainframe->enqueueMessage(JText::_('CC IMAGE FILE NOT SUPPORTED'), 'error');
 
            return false;
        }

        } else {
            // @todo: configurable width?

            // Get a hash for the file name.
            $profileType = $my->getProfileType();
