EasyBadge image format

In EasyBadge the images, when stored in a database, are JPEG files with a 30-byte header. The format of the header is:

private struct DigitalIdImageHeader

{

    public int Magic;  // 0x05082011

    public int Length; // size of header plus image data

    public short Width; // in pixels

    public short Height;

    public short Shades;

    public short ImageType;

    public short CompressionType; // must be 4

    public int Crc;

    public int Info2;

    public int Info3;

}

The image data, directly taken from a JPEG file follows the header.
