This tool allows you to select a custom thumbnail for embeds that don’t have a proper lead image, i.e. Twitter, Instagram, Soundcloud, etc. This thumbnail is then displayed in our curation module, assorted recirculation modules, and social shares.
To assign a custom thumbnail, click the embed to open the inline toolbar. On the toolbar, click the image icon to open an image upload modal.Full instruction on how to use custom thumbnails can be found in the Product team’s Custom Thumbnail Upload guide.
