  $host = 'localhost'; // endereço do servidor de banco de dados.
    $dbname = 'tabela'; //nome de sua base de dados
    $user   = 'root'; // seu usuário do banco
    $pass   = 'senha'; // sua senha do banco
    $pdo = new PDO('mysql:host='.$host.';dbname='.$dbname,$user,$pass);

    $lista = $pdo->prepare('SELECT count(*) total from imagem') or trigger_error($pdo->error);
