+#### Image link generation
+
+_Requirement: the `img` directive can make an image be a link._
+
+The [ikiwiki img
+directive](http://ikiwiki.info/ikiwiki/directive/img/) allows
+arguments:
+
+> The link parameter is used to control whether the scaled 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, or
+> "link=http://url" to link to a given url.
