A:

You can try this syntax 
<!DOCTYPE html>
<html>

  <title>Leaflet Quick Start Guide Example</title>
  <meta charset="utf-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <link href='https://api.tiles.mapbox.com/mapbox.js/v1.6.2/mapbox.css' rel='stylesheet' />
 </head>
<body>
 <div id="map" style="width: 1000px; height: 1000px"></div>

 <script src='https://api.tiles.mapbox.com/mapbox.js/v1.6.2/mapbox.js'></script>
 <script>

  var map = L.mapbox.map('map');
  L.tileLayer('http://eccoilmoro.github.io/Mappa-Redditi-IRPEF-2012-/tiles-mappa-redditi-2012/{z}/{x}/{y}.png', {
   "attribution": "franco"
    }).addTo(map);

  map.setView(new L.LatLng(39.5, 9), 6);
