Having a <code>favicon.*</code> in your root directory is automatically detected by most browsers. You can ensure it's detected by using:

<pre><code> &lt;link rel="icon" type="image/png" href="/path/image.png" /&gt;
</code></pre>

Personally I use .png images but most formats should work.

Favicon must be an <a href="http://en.wikipedia.org/wiki/ICO_%28icon_image_file_format%29" rel="nofollow noreferrer">.ico file</a> to work properly on all browsers.

Modern browsers also support PNG and GIF images.

I've found that in general the easiest way to create one is to use a freely available web service such as <a href="http://favicon.cc/" rel="nofollow noreferrer">favicon.cc</a>.

To also support touch icons for tablets and smartphones I prefer the approach of <a href="https://github.com/h5bp/html5-boilerplate/blob/master/src/doc/html.md#favicons-and-touch-icon" rel="nofollow">HTML5Boilerplate</a>

More information on touch icons can be found in <a href="http://mathiasbynens.be/notes/touch-icons" rel="nofollow">this article</a>.

With the current status of browser-support you don't even have to add the HTML tag for the favicon in your document. The browsers will search automaticly a list of files, see this example for iOS:

<blockquote>
 If no icons are specified in the HTML, iOS Safari will search the
 website’s root directory for icons with the apple-touch-icon or
 apple-touch-icon-precomposed prefix. For example, if the appropriate
 icon size for the device is 57 × 57 pixels, iOS searches for filenames
 in the following order:
 
 <ol>
 <li>apple-touch-icon-57x57-precomposed.png</li>
 <li>apple-touch-icon-57x57.png</li>
 <li>apple-touch-icon-precomposed.png</li>
 <li>apple-touch-icon.png</li>
 </ol>
</blockquote>

My advise is to not include a favicon in your document, but have a list of files ready in the root website:

<ul>
<li>apple-touch-icon-114x114-precomposed.png</li>
<li>apple-touch-icon-144x144-precomposed.png</li>
<li>apple-touch-icon-57x57-precomposed.png</li>
<li>apple-touch-icon-72x72-precomposed.png</li>
<li>apple-touch-icon-precomposed.png</li>
<li>apple-touch-icon.png <code>(57px*57px)</code></li>
<li>favicon.ico <code>HiDPI (32x32px)</code></li>
</ul>

When you download a template from <a href="http://html5boilerplate.com/" rel="nofollow">html5boilerplate.com</a> these are all included, you just have to replace them with your own icons.
