This plugin adds a favicon link to the document head section.
There are no options. The link is always added when the plugin is enabled.
The <code>favicon.ico</code> file needs to be uploaded to the site’s root 
directory. If you do not know how to do this, you should have a look at 
one of the other favicon plugins.
