This plug-in is great, as it can be just used in conjunction with existing WordPress festures, such as the gallery shortcode. However, there is a major feature missing. Users simply can't navigate through galleries when using highslide.
As a universal solution which would greatly extend the plug-in not only for highslide but possibly to other scripts, I suggest a feature where users should be able to specify code to be added to the anchor or image <img>.
For example, I would like to add the following into the anchor of each picture in my gallery: onclick="return hs.expand(this, config1 )">
For example:
<a href="highslide/sample-images/thumbstrip01.jpg" class="highslide"
title="Caption from the anchor's title attribute"
onclick="return hs.expand(this, config1 )">
<img src="highslide/sample-images/thumbstrip01.thumb.jpg" alt=""/>
</a>
If each item in a WordPress gallery have the onclick attribute, then the gallery works fine!
