I use ePhoto by Elegant Themes. It's suited my needs pretty well over the years, however, when I updated the jQuery plugin last week the nav bar drop downs stopped working, but now the slideshow works on my wedding page!
I've contacted a techie who told me how I need to fix it in the .php, I just have not had the time. I think I'll work on it again tonight though.
I too am interested to hear of others out there.
