# Why Are Images Failing to Load in HTML Email Campaigns?

> Fix image loading failures in HTML email campaigns caused by parentheses in URLs by wrapping them in single quotes within CSS URL syntax.

## Problem

When creating an HTML Email campaign, the uploaded image URLs may not appear in the email preview or during testing.

## Explanation

The issue occurs when the URL contains parenthesis.

## Solution

Use single quotation marks within the `URL()` syntax when adding the image, such as for a background color.

## Example

To fix this, wrap the URL in single quotation marks to prevent syntax errors. The correct CSS code should follow this format:

<CodeGroup>
  ```css Code wrap theme={null}
  background-image:
    url('https://abc....');
  ```
</CodeGroup>
