Usage:

In your HTML:

<img src="/IMAGESDIR/u.gif" name="imgfirst" width="9" height="9" border="0" >
<a href="#first" onClick="shoh('first');" >Customer Support</a>

<div style="display: none;" id="first" >

Here is the content you want to collapse or expand. You can place tables here, images, anything.

</div>

Alternate example (may be placed on the same page with no interference):

<img src="/IMAGESDIR/u.gif" name="imgsecond" width="9" height="9" border="0" >
<a href="#second" onClick="shoh('second');" >Customer Support</a>

<div style="display: none;" id="second" >

Here is more content you want to collapse or expand. You can place tables here, images, anything.

</div>

IMAGESDIR is where your icons reside.

shoh('id'); will hide if shown and show if hidden.
