    How to add an image, gif or embed a Youtube video

    You can't upload files from your device - media has to be linked from a URL.

    • YouTube video: paste a plain YouTube link on its own line.
      https://www.youtube.com/watch?v=VIDEO_ID
      Renders as an embedded YouTube video. Source links will be automatically added.
    • Looped GIF from YouTube: add a ?START-END range (max 10s).
      https://youtu.be/VIDEO_ID?3:50-3:53
      The YouTube video will be automatically be converted to a gif, in the time range. Source links will be automatically added.
    • Still image from YouTube: add a single ?TIMESTAMP.
      https://youtu.be/VIDEO_ID?0:42
      The YouTube still frame will be automatically be converted to an image. Source links will be automatically added.
    • Image from the web: paste a direct link to the image file on its own line - the URL must end in .jpg/.png/.gif/.webp. A link to a page containing an image won't work.
      https://example.com/pic.jpg
      The image will be automatically downloaded. Source links will be automatically added.
    Header image & article details Optional - header, skill check, tags & prerequisites.

    Paste a direct image URL, or turn a YouTube moment into the header with the button. Leave empty to keep the current one.
