# Switch an Item's Primary Image

Use this method to update an item's primary image. 

### Usage in your script

{% tabs %}
{% tab title="First Tab" %}

```javascript
const updatedItem = await alturaItem.updatePrimaryImage(IMAGE_INDEX);
```

{% endtab %}

{% tab title="TypeScript" %}

```typescript
const updatedItem IAlturaItem = await alturaItem.updatePrimaryImage(IMAGE_INDEX);
```

{% endtab %}
{% endtabs %}

{% hint style="info" %}
`Remember, imageIndex` starts at 0 and **not** 1. Therefore the highest `imageIndex` is `imageCount - 1`
{% endhint %}
