Web

Web previews will automatically use OpenGraph information to populate the preview. If an image is present, LinkPreview will default to that, otherwise show a non-interactive web view of the page.

Twitter

Twitter previews will automatically be used if the OpenGraph response returns site_name=Twitter. The Twitter preview automatically adjusts to handle basic tweets and up to four images.
