adding HTML referneces to a wordpress page

How can I reference things like images or Javascript inside of a wordpress page?

I want to insert HTML code for example

<div id=”content”><img src=” img/logo.gif” alt=”LOGO” width=”240″ height=”32″ />

in a wordpress page. Of course when I place the “logo.gif” image in the img folder on my root directory, it doesn’t reference it and shows up as a broken image.

The same with JS

<script src=”js/search.js” type=”text/javascript”></script><script src=”js/pagination.js” type=”text/javascript”></script>

How can I actually reference this using HTML within a wordpress page? Is it even possible?
