# --description--
The last few challenges showed that each object in the JSON array contains an `imageLink` key with a value that is the URL of a cat's image.
When you're looping through these objects, you can use this `imageLink` property to display this image in an `img` element.
Here's the code that does this:
`html += "<img src = '" + val.imageLink + "' " + "alt='" + val.altText + "'>";`
# --instructions--
Add code to use the `imageLink` and `altText` properties in an `img` tag.
# --hints--
You should use the `imageLink` property to display the images.
```js
assert(code.match(/val\.imageLink/g));
```
You should use the `altText` for the alt attribute values of the images.
```js
assert(code.match(/val\.altText/g));
```
