/**
 * Syntax for images is like the syntax for links, with one difference.
 * Instead of link text, we have an image description.
 * The rules for this are the same as for link text, except that
 *
 *  a) an image description starts with '![' rather than '[', and
 *  b) an image description may contain links.
 *
 * An image description has inline elements as its contents. When an image is
 * rendered to HTML, this is standardly used as the image’s alt attribute.
