title: Render Images from Data Sources
challengeType: 6
forumTopicId: 18265

## Description
<section id='description'>
The last few challenges showed that each object in the JSON array contains an <code>imageLink</code> key with a value that is the URL of a cat's image.
When you're looping through these objects, you can use this <code>imageLink</code> property to display this image in an <code>img</code> element.
Here's the code that does this:
<code>html += "&lt;img src = '" + val.imageLink + "' " + "alt='" + val.altText + "'&gt;";</code>
</section>

## Instructions
<section id='instructions'>
Add code to use the <code>imageLink</code> and <code>altText</code> properties in an <code>img</code> tag.
</section>

## Tests
<section id='tests'>

```yml
tests:
  - text: You should use the <code>imageLink</code> property to display the images.
    testString: assert(code.match(/val\.imageLink/g));
  - text: You should use the <code>altText</code> for the alt attribute values of the images.
    testString: assert(code.match(/val\.altText/g));

```
