# Web Push: Rich Message

When you select a layout with the rich message option, you can enhance your Web Push notification by adding a large image below the message description. This provides a more engaging visual experience for your users.

You have two options for adding a rich image:

- Upload a static image from your device
- Provide a dynamic image URL (e.g., product-related visuals)

## Dynamic Image with Fallback

If you use a dynamic image URL, it's essential to define a fallback image. This ensures your Web Push notification still displays correctly if the dynamic image value is missing or fails to load.

> [!WARNING]
> The image URL must begin with **https://**. Browsers block non-secure (http) image sources in Web Push notifications.

## Image Requirements

To ensure proper rendering across devices and browsers:

- Recommended size is 720 × 360 pixels (2:1 aspect ratio)
- Maximum size is 1024 × 512 pixels
- File size limit is less than 500 KB

If the dynamic image fails to load, the fallback image will be used automatically.

> [!WARNING]
> Firefox on Windows 11 doesn’t support Rich Push.
