I’ve tried putting the following lines in header.php just after the head tag, just before the end head tag, and in the middle. In each case the comment lines and the meta tag line appear, but the link lines show up as blank in the source:
<!– Start of favicon links –>
<meta name=”keywords” content=”This,is,a,test”>
<link rel=”icon” href=”http://austintango.org/favicon.ico” type=”image/x-icon”>
<link rel=”shortcut icon” href=”http://austintango.org/favicon.ico” type=”image/x-icon”>
<!– End of favicon links –>
