Notes and caveats
- Sponsored Content in the LinkedIn feed; each card is checked as an image. Videos can't be added to carousel image ads. LinkedIn publishes no safe zones for its ads. The Ads Guide's summary lists JPG or PNG; the help article's JPG, PNG and non-animated GIF are used (decision D34).
