how to enable browser caching in jsf

I have created a web application using JSF 2.0. I got feedback from my friend saying I should do "Browser Caching" as I have many images.

However I don't know how to do same in JSF. Any idea/ hint would be appreciated.

Concept on what to be done would also work.

Just use <h:graphicImage name="..."> instead of <img src="...">. This way the default JSF resource handler will instruct the browser to cache them for 1 week by default, which is configureable with an implementation dependent context parameter, which is the following in case of Mojarra:

<context-param>
    <param-name>com.sun.faces.defaultResourceMaxAge</param-name>
    <param-value>3628800000</param-value> <!-- 6 weeks -->  
</context-param>

Note, the same applies when using <h:outputScript> and <h:outputStylesheet> instead of <script> and <link rel="stylesheet">.
