Favicon IE8

[Magiccupcake]

I have made a website http://happytails-il.org

I have been trying to add a favicon, but with cannot get it working in IE8(I have not tested other versions of IE). It works perfectly fine in firefox. The site is done with joomla. with the exception of a couple of pages.

I have no idea what I am doing wrong. I have tried using favicon.ico and favicon.png in a couple different directories.

I have added different combinations of the below codes, but nothing works in IE8.

<link rel="shortcut icon" type="image/x-icon" href="/favicon.png" />
<link rel="icon" type="image/x-icon" href="/favicon.png" />
<link rel="shortcut icon" type="image/x-icon" href="/favicon.ico" />
<link rel="icon" type="image/x-icon" href="/favicon.ico" />

any help would be greatly appreciated.
