I just released Lightbox Plus 1.6.2 to address issues with jQuery conflicts and implementation or shortcode galleries in templates.  Here are the latest changes.

1.6.2

• Added jQuery.noConflict() to the initiator to hopefully eliminate issues with other jQuery libraries loading and causing conflicts.
  • Changed jQuery $ variable to $lbp to give a unique constructor.
• Added replacement shortcode gallery method to allow Lightbox Plus to work with shortcode galleries called via the echo do_shortcode('[ gallery link="file" size="thumbnail"]'); method in templates.
  • Replacement shortcode gallery function automatically adds rel="lightbox" or class="cboxModal" as selected in options.
• Added code to automatically cleanup doubled title tags from shortcode galleries.
• Added quicklinks to the plugin listing on the plugin page.
• Some minor UI tweaks to the admin page.

You can get it from WordPress.org or 23systems download Lightbox Plus 2.4.6 directly.
