The following table holds the images and captions.
Place the table in your page where you want the slideshow
to appear. Follow the instructions for each table cell.
//-->
<table border=0 cellpadding=0 cellspacing=0>
<tr>
<!--
The next table cell holds the images.
Set cell and image width and height the same.
The img src must have name=PictureBox in its
tag. Usually the first image in the Picture
array in the script is used here.
//-->
<td width=350 height=280>
<img src=Image001.jpg name=PictureBox width=350 height=280>
</td>

<tr>
<!--
The next table cell holds the captions.
This table cell must have id=CaptionBox and
class=Caption in its tag. The default caption
shows whilst loading in all browsers; NS4
will show only the default caption, throughout.
//-->
<td id=CaptionBox class=Caption align=center bgcolor=#fedcba>
