// A JPEG's Multi-Picture index lists the images stored after the primary: previews, stereo views, a gain map.
using Raster photo = Raster.Load("ultrahdr.jpg");
MpfData? index = ((JpegDetails)photo.Metadata.FormatDetails!).MultiPicture;
foreach (MpfImage image in index?.Images ?? [])
{
    Console.WriteLine($"{image.Type}: {image.Length:N0} bytes at {image.Offset:N0}");
}

// LoadAll gives every JPEG image the index lists, the primary first; a plain JPEG gives one.
using RasterList all = Raster.LoadAll("ultrahdr.jpg");
