# --description--

Innanzitutto, aggiungi una nuova immagine sotto quella esistente. Imposta l'attributo `src` su `https://cdn.freecodecamp.org/curriculum/cat-photo-app/running-cats.jpg`.

Sarebbe bello se questa immagine potesse essere larga esattamente come lo schermo del nostro telefono.

Fortunatamente, con Bootstrap, tutto quello che dobbiamo fare è aggiungere la classe `img-responsive` alla tua immagine. Fai questo, e l'immagine dovrebbe adattarsi perfettamente alla larghezza della pagina.

# --hints--

Dovresti avere un totale di due immagini.

```js
assert($('img').length === 2);
```

La tua nuova immagine dovrebbe essere sotto la vecchia e avere la classe `img-responsive`.

```js
assert($('img:eq(1)').hasClass('img-responsive'));
```

La tua nuova immagine non dovrebbe avere la classe `smaller-image`.

```js
assert(!$('img:eq(1)').hasClass('smaller-image'));
```

La tua nuova immagine dovrebbe avere un attributo `src` di `https://cdn.freecodecamp.org/curriculum/cat-photo-app/running-cats.jpg`.

```js
assert($('img:eq(1)').attr('src') === 'https://cdn.freecodecamp.org/curriculum/cat-photo-app/running-cats.jpg');
```

Il tuo nuovo elemento `img` dovrebbe avere una parentesi angolare di chiusura.

```js
assert(
  code.match(/<img/g) &&
    code.match(/<img[^<]*>/g).length === 2 &&
    code.match(/<img/g).length === 2
);
```
