Adding a Flickr Set

  1. Get a flickr api key and enter it in the Configuration → Flickr Settings page.
  2. Go to Configuration → File Types and click on the Manage file display for the Video row.
  3. In enabled displays check "Flickr Photoset".
  4. Then under "Display Settings" click Default display, enable Flickr Photoset and configure the width, height, and autoplay.
  5. I configured a Preview display and enabled Flickr Preview image. Under the Flickr Preview Image, set the image preset that you want to use.
  6. Go Structure → Content Types and either create new type or edit the type to which you want to add flickr albums.
  7. I added a field called album_3rdparty of type file with widget Embedded Media Field.
  8. Under Manage Display for this field for the Default display set format to Rendered File and mode to Default.
  9. For the Teaser Display I left it hidden for now but you want to set it to a different mode if you want to display the preview image in the teaser instead of the full photoset.
