Tip: The poster image in a Table of Contents view is responsive to screen size. This means it will re-crop as you change to different size screens. We suggest you choose files that have a strong visual interest in the center of the frame, so that it looks good on multiple devices. Long horizontals, like panoramas, will frequently work best.
