# Remote​Asset

***

## Examples

The following examples contain code snippets that either fail or pass this check.

### ✗ Fail

In these examples, multiple connections are competing for resources, are accelerating download independently and are improperly prioritized.

The following example retrieves assets from multiple CDNs:

```liquid
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js" defer></script>
{{ "https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" | stylesheet_tag }}
<img src="https://example.com/heart.png" alt="" />
```

The following example doesn't use the [`image_url` filter](https://shopify.dev/docs/api/liquid/filters/image_url) to retrieve the image.

```liquid
<img src="/content/assets/images/{{ image }}" alt="" />
```

### ✓ Pass

In the following examples, JavaScript, CSS and images are all loading from the same connection. The browser and CDN can properly prioritize which assets are downloaded first while maintaining a "hot" connection that downloads fast.

This can be done by downloading the files from those CDNs directly into your theme's `assets` directory and using the [`image_url` filter](https://shopify.dev/docs/api/liquid/filters/image_url) for images, as in the following example:

```liquid
<script src="{{ 'theme.js' | asset_url }}" defer></script>
{{ 'bootstrap.min.css' | asset_url | stylesheet_tag }}
<img src="/content/assets/images/{{ image | image_url: width: 500 }}" alt="" />
```
