This is an example gallery description. You can list images explicitly (as above, with per-image alt, optional nsfw, optional width/height for external images, and an optional feature flag for the mosaic layout) or use galleryFolder: my-folder to pull every image under galleries/my-folder/ from the image manifest.

Set layout: in the frontmatter to choose the arrangement: justified (default, tiled mosaic), grid, masonry, or mosaic.
