Which image does Shopify use when you share a store link?

Which image does each page share?

On all of the free themes from Shopify, a product, collection or blog post link shows that page's featured image. Pages without one, such as your homepage, show your store's Social sharing image, per Shopify's help. To change what those links show, change the featured image on that product, collection or blog post.

Shopify.dev gives the same rule for the page_image object, and if a theme doesn't include its own og:image tags for a page, Shopify generates them from page_image.

To set the Social sharing image, click Add image (or Change image if one is already set) in the Social sharing image and SEO section of Online Store > Preferences, then Save.

Why does a different image show up?

Shopify's help gives this priority order, so check from the top:

1. Theme code images, hard-coded in your theme files, come first.
2. Theme settings images for social media or checkout; some themes show only these.
3. Online Store Preferences image, the fallback when no other image can be found.

If the Preferences field is blank but a picture still appears, it might be coming from your theme settings, such as Theme settings > Social media (or Social sharing), or from a logo: Shopify might use your header logo, then Theme settings > Checkout > Logo. If the logo Shopify uses is transparent or doesn't meet the recommended dimensions, Shopify pads it with your Theme settings > Colors > Background color (or the checkout's background color if that setting isn't available).

Why does the old image still show after you change it?

Facebook “stores images for a number of days before checking for updates,” so Shopify's help suggests refreshing the preview with Facebook's Sharing Debugger. Re-submitting your sitemap is the help's fix for a different case, an outdated image “in search engine results.”
