# How do I change my social share image?

Topic: [Sharing and embedding](https://mindstamp.com/help/sharing) · Updated: 2026-09-25

## Short answer

The preview image for a shared link is the video’s thumbnail. Open the video’s **Design**, go to **Branding**, and change **Thumbnail**. New shares use the new image. A social network can keep showing the old image for a link it has already read, until you refresh its cache.

## Steps

1. Make a landscape image with one clear subject and little small text.
2. Open the video and select **Design**.
3. In the **Branding** section, find **Thumbnail** and select **Change**, or **Add Thumbnail** if there is none.
4. Upload or choose the image. The change saves automatically.
5. Open **Share** and check the thumbnail in the page header.
6. Paste the share link into the social network’s link preview tool and ask it to fetch the link again.

## Image size

Mindstamp does not crop the image. Each social network crops it for its own cards. Most networks show a wide card and recommend an image at least 1200 pixels wide. Keep text and faces near the center so a crop does not cut them.

## Why the old image still shows

- Social networks and chat apps save a copy of a link’s preview the first time they read it. A post you made before the change keeps the old image.
- Use the network’s own tool to refresh a link, such as the Facebook Sharing Debugger or the LinkedIn Post Inspector.
- Some apps have no refresh tool. Their cache expires after some time.

## The thumbnail has other uses

The same thumbnail shows in the player before the video starts when **Use Looping Preview** is off. It is also the image in the **Popout** embed and in the structured data from **Include SEO metadata**. Check those places after you change it.

## Change the title and description too

The preview card also shows a title and description. See [control how a video appears when shared](https://mindstamp.com/help/how-do-i-control-how-my-video-appears-when-shared-socially-can-i-change-the-generated-title-image-and-description).
