The page_image object
Returns an image drop for the relevant image to be displayed in social media feeds or search engine listings.
For product pages, collection pages, and blog posts, the page_image is the resource's featured image if it exists. For example, a product page's page_image is the same as its product.featured_image. If a featured image does not exist, then the page_image is based on the store's social sharing image set in the admin.
