Ah, come on folks. ?? I want to know about this too. There must be something.
Teejayuu, if nothing else you can try to use fGallery. There’s no demo that I’ve seen so far, but I installed it and it did seem to have lightbox support etc. I couldn’t get it to work with subgalleries though. I suppose you could just create a page with a listing of categories. The categories could then link to posts that link to fGallery. I don’t know if that even makes sense. Right now I’m trying to just use iMP Auto Slimbox. It automatically converts img tags so that they include the required lightbox code.
