I fixed my troubles and your plugin works great. No need to respond.
Note to Others who do not see the lightbox:
Your theme developer or your gallery plugin may have encoded a custom REL value into all gallery image links. If your lightbox does not work at all, view source on any gallery thumbnail image. Whatever value is entered in the REL tag (example, rel=”rgg”) must be entered in the Responsive Lightbox General Settings page, 2nd field from top, “Selector.”
Then you should be golden.
