Choosing a social media image
When you share a link to your online store on social media, such as on Facebook or Pinterest, you can display a thumbnail image in your post.
Showing featured images
For all of the free themes from Shopify, when you post a link from your online store to social media, the featured image for that page is shown. For example, if you post a link to a product page, then the product’s featured image is shown.
There are a number of page links that do not have featured images, like your homepage or an "About us" page. In these cases, a single social sharing image is shown.
Setting the social sharing image in your admin
When you share a link to your store on social media, an image is usually shown in your post.
Some themes have a social sharing image setting within them. If an image has been set in the theme settings, that image will appear on your social post. This setting always overrides any social sharing image settings from your online store preferences.
In Online Store > Preferences, you can add a default image to be used when another relevant image can't be found.
If you added a logo to your store in your theme settings, then Shopify uses your logo as your default social sharing image.
From your Shopify admin, go to Online Store > Preferences.
Find the Social sharing image section.
To upload a new image, click Add image. To change the existing image, click Edit > Change image.
Select the image from your computer that you want to show on social media.
The page title and meta description for your store might be shown alongside your image when you post to social media. This information can be edited in the Home page title and Home page meta description fields in Online store > Preferences. These values affect your SEO, so you should consider any changes carefully.

Updating your images
Shopify's free themes use Open Graph tags to give social media platforms information about your website. Open Graph is used by Facebook, Twitter, LinkedIn, Pinterest, and other services.
Open Graph information, which is managed by Facebook, is stored for a number of days before checking for any updates. If you change your social media image, then use the Facebook Sharing Debugger to refresh the information that is saved for your page links.
