I created apple icons and uploaded them to the images folder. I've placed the following code in the header file, but the icons are not working.
<link rel="apple-touch-icon" sizes="57x57" href="images/apple-icon-57x57.png" />
<link rel="apple-touch-icon" sizes="72x72" href="images/apple-icon-72x72.png" />
<link rel="apple-touch-icon" sizes="114x114" href="images/apple-icon-114x114.png" />
<link rel="apple-touch-icon" sizes="144x144" href="images/apple-icon-144x144.png" />
Why is it not working? Do I have the code in the wrong spot?
