    <p>
        This is a demonstration of the zoom in thumbnail mode with some custom CSS (the <i>border-radius</i> property) which facilitates
        making the thumbnail circular.

    <p>
        Remember that browser support for this is limited - currently (5th September 2011) only Firefox 4+ and IE9+ support it.
