STEP 2.
Calling the Image Popup from Links in Your Page

This is the form of the function:

popImage("url_of_image","title_of_image")

Use the relative or absolute path of the image where we show
url_of_image.  This is the url of the image you wish to show
in the auto-sizing popup window.

Use any text you wish where we show title_of_image. This is 
the title that will appear in the titlebar of the popup. (Note:
do not use single- or double-quotes within a title.)


Caution:  Be careful to place both values within quotes.
See the samples below.


Example 1:  Launching from a text link

<a href="javascript:popImage('http://SomeSite.com/SomeImage.gif','Some Title')">
Click Here
</a>


Example 2:  Launching from an image link

<a href="javascript:popImage('http://SomeSite.com/SomeImage.gif','Some Title')">
<img src="YourImage.gif" border="0">
</a>


Example 3:  Launching from a form button

<form>
<input type="button" value="Click Here" onClick="popImage('SomeImage.gif','Some Title')">
</form>
*/
