<p>This test does a few things:
<ul>
<li>It has a couple of:
<ul>
<li>Images: <IMG SRC="http://zabadubop/layers/tests/mzcolor.gif"> and
<IMG SRC="http://peoplestage.netscape.com/kipp/nerdly_int.gif">.
<li>Links to <a href="http://home.netscape.com">Netscape</a> and
<A HREF="http://peoplestage.netscape.com/kipp">Kippy's Home Page</A>.
<li>and Anchors to <a NAME="anchor1">here</A> and
<A name="anchor2">here</a>.
</ul>
<li>It dumps (check the JS console) the images, links and anchors using
the document.images, document.links and document.anchors arrays.
<li>Then it removes one of the images.
<li>Dumps the images array again. This is to prove that the images array
is live.
<li>Adds back the image.
<li>And the dumps the images array again. The image arrays order should
now be different.
<li>It gets a list of LIs (using getElementsByTagName()) and prints
out all their tagNames. There should be 10.
</ul>
