You can also pass `alt`, `class` and `id` parameters. These are passed through
unchanged to the html img tag.
+The `link` parameter is used to control whether the scaled down image links
+to the full size version. By default it does; set "link=somepage" to link
+to another page instead, or "link=no" to disable the link.

You can also set default values that will be applied to all later images on
the page, unless overridden. Useful when including many images on a page.
