I've posted a new build for Simple Gallery in the downloads section (members only).

New Functionality Includes:-

• Implementation of a new jQuery lightbox that supports:-
  • Starting the slideshow before the page loads.
  • Reduced flicker
  • Localization (images replaced with text)
  • Long descriptions that will no longer run off the lightbox.
  • Reduced script size
  • Better support with other 3rd party scripts.

Thanks again for all your feedback!
