Edit media thumbnails – Theming


About

Manage how your media is visually represented by editing its thumbnails. You can upload new thumbnails, select a frame (for video), set the default thumbnail, preview, download, or remove thumbnails.

These settings are managed in the Thumbnail tab when editing a media entry.

Thumbnail editing isn’t available for image media.

Who can use this

  • Media owners
  • Co-editors

Access the Thumbnail tab

  1. From the user menu, select My Media
  2. The 'My Media' page displays.

  3. Click the three dots to the right of the desired media and select Edit.

    The edit media page opens on the Details tab by default, with a left-hand navigation.

The page displays the default thumbnail, which is created automatically when the media is uploaded. This is the thumbnail shown across the platform wherever the media appears.
