# --description--

Next, give each `img` a `src` attribute according to its order in the document. The first `img` should have a `src` of `https://cdn.freecodecamp.org/curriculum/css-photo-gallery/1.jpg`. The rest should be the same, except replace the `1` with the number the `img` is in the document.

# --hints--

All nine of your `img` elements should have a `src` attribute.

```js
const images = [...document.querySelectorAll('img')];
assert.isTrue(images.every(image => image.getAttribute('src')));
```

Your first `img` element should have `https://cdn.freecodecamp.org/curriculum/css-photo-gallery/1.jpg` set as the `src` attribute value.

```js
assert.equal(document.querySelectorAll('img')?.[0]?.getAttribute('src'), 'https://cdn.freecodecamp.org/curriculum/css-photo-gallery/1.jpg');
```

Your second `img` element should have `https://cdn.freecodecamp.org/curriculum/css-photo-gallery/2.jpg` set as the `src` attribute value.

```js
assert.equal(document.querySelectorAll('img')?.[1]?.getAttribute('src'), 'https://cdn.freecodecamp.org/curriculum/css-photo-gallery/2.jpg');
```

Your third `img` element should have `https://cdn.freecodecamp.org/curriculum/css-photo-gallery/3.jpg` set as the `src` attribute value.

```js
assert.equal(document.querySelectorAll('img')?.[2]?.getAttribute('src'), 'https://cdn.freecodecamp.org/curriculum/css-photo-gallery/3.jpg');
```

Your fourth `img` element should have `https://cdn.freecodecamp.org/curriculum/css-photo-gallery/4.jpg` set as the `src` attribute value.

```js
assert.equal(document.querySelectorAll('img')?.[3]?.getAttribute('src'), 'https://cdn.freecodecamp.org/curriculum/css-photo-gallery/4.jpg');
```

Your fifth `img` element should have `https://cdn.freecodecamp.org/curriculum/css-photo-gallery/5.jpg` set as the `src` attribute value.

```js
assert.equal(document.querySelectorAll('img')?.[4]?.getAttribute('src'), 'https://cdn.freecodecamp.org/curriculum/css-photo-gallery/5.jpg');
```

Your sixth `img` element should have `https://cdn.freecodecamp.org/curriculum/css-photo-gallery/6.jpg` set as the `src` attribute value.

```js
assert.equal(document.querySelectorAll('img')?.[5]?.getAttribute('src'), 'https://cdn.freecodecamp.org/curriculum/css-photo-gallery/6.jpg');
```

Your seventh `img` element should have `https://cdn.freecodecamp.org/curriculum/css-photo-gallery/7.jpg` set as the `src` attribute value.

```js
assert.equal(document.querySelectorAll('img')?.[6]?.getAttribute('src'), 'https://cdn.freecodecamp.org/curriculum/css-photo-gallery/7.jpg');
```

Your eighth `img` element should have `https://cdn.freecodecamp.org/curriculum/css-photo-gallery/8.jpg` set as the `src` attribute value.

```js
assert.equal(document.querySelectorAll('img')?.[7]?.getAttribute('src'), 'https://cdn.freecodecamp.org/curriculum/css-photo-gallery/8.jpg');
```

Your ninth `img` element should have `https://cdn.freecodecamp.org/curriculum/css-photo-gallery/9.jpg` set as the `src` attribute value.

```js
assert.equal(document.querySelectorAll('img')?.[8]?.getAttribute('src'), 'https://cdn.freecodecamp.org/curriculum/css-photo-gallery/9.jpg');
```
