Adding Media To add your own non-video media to a page (e.g., images and other file types like PDFs), you must first upload the file(s) to the Media Library. Next, you will use Sitecore's Content Editor to either: Insert images on a page, and add classes, captions, or image lightboxes; embed videos from external sources (e.g., YouTube, Vimeo, Drexel Streams) and display other iFrame media like social media widgets; create an internal Sitecore link to download a file (e.g., PDF or PPT file).
