To create a media placeholder in Figma that can be replaced in deckd, add an image and name the layer media. Ensure you use an actual image file, as deckd will recognize it as a swappable placeholder, allowing users to replace it with supported media types.

If an image should remain fixed in deckd, name it anything other than media. This is useful for brand visuals, logos, or illustrations that should stay consistent across assets.

Please use web-optimized images to keep file sizes small and ensure faster loading times.
