Makeing changes to the script imgpreview

[CooKachoo]

Does anyone know how I can modify this script so that so that it will preview an image without requiring me to link to that image? If that makes no sense I do have an example below.


<li><a href="http://site.com" target="_blank"><img src="hs.png" /></a></li>

This is what I would like to add the "imgpreview" script to, but in order to do that I would have to change the link to "site.com" to the location of the image I would like to preview.

Any help would be appreciated. Here's the script.
