Script: Frog JS Image Gallery (http://www.dynamicdrive.com/dynamici...ogjs/index.htm)

This script is working beautifully, I'm just having troubles configuring one small thing. The enlarged image (not the thumbnail) can click to an additional link. Unfortunately it automatically opens it in the same exact window, which is rather small for viewing. I can't seem to figure out how to get it to open in a new window, especially since the rel attribute is already being used here. Here's the html section I'm referring to:
Code:
<a href="acrylics_50.jpg" title="White Woodland flowers" rel="http://www.new_window_link.com">
<img src="acrylics_50_thumbnail.jpg" </a>

<a href="acrylics_51.jpg" title="White Irises with dark ground" rel="http://www.new_window_link2.com">
<img src="acrylics_51_thumb.jpg" </a>
The frog.js file is way too long to paste into my post, unless its necessary. It's on the dynamicdrive link above. Please let me know if I'm not being clear about my problem or if I can offer any more information.

Thanks in advance for trying to help!!!
