I go for a belt and braces approach here.
I create a 32x32 icon in both the .ico and .png formats called favicon.ico and favicon.png. The icon name doesn't really matter unless you are dealing with older browsers.
- Place
favicon.ico at your site root to support the older browsers (optional and only relevant for older browsers.
- Place favicon.png in my images sub-directory (just to keep things tidy).
- Add the following HTML inside the
<head> element.
<link rel="icon" href="/images/favicon.png" type="image/png" />
<link rel="shortcut icon" href="/favicon.ico" />
Please note that:
- The MIME type for
.ico files was registered as image/vnd.microsoft.icon by the IANA.
- Internet Explorer will ignore the
type attribute for the shortcut icon relationship and this is the only browser to support this relationship, it doesn't need to be supplied.
