Although links provide the power of the web, they are actually one of the simpler HTML elements, the <A> (anchor) element, formatted as:
<A href="URL or anchor name"> clickable text or image </A>
To use an image rather than text, the format is:
<A href="URL or anchor name"> <img src="images/logo.gif" alt="logo"> </A>
Notice that the construction is the same with the exception of what becomes clickable (text or image).
