## Change the social media image

- Go to your dashboard.

- Click **Manage auction**. That opens **Campaign Hub**.

- In the left sidebar, under **CAMPAIGN**, click **Campaign Settings**.

- Open the **Page Branding** tab.

- Open **Main Banner**. The heading is **Customize Your Event Banner**.

- Choose **Upload Custom Banner**.

- Click **Upload Banner** (or **Change Banner** if one is already there).

- Use a **1920x600px** image. **PNG**, **JPG**, **GIF**, or **WEBP**.

The other banner options on that row are **Create Custom Banner**, **Text Banner**, and **No Banner**. For a photo share image, use **Upload Custom Banner**.

## Check the share preview

- Click **Promote** in the top right (or open Promote tools).

- Find **Your Auction Link Preview**.

- Confirm the image, auction name, and subheadline.

That preview is generated from your current banner and Event Design settings. If you do not see your photo, upload a banner under **Page Branding** as above.
