The coder of Arylia sold his share... he runs some babelogs (I think pornspinner.com is one)
I own (and coded) Gallery Daemon. I don't have a public demo... but if you hit me on ICQ then I can show you a copy on a working site.
If you are looking to make 2-3 galleries per day for a blog then I suggest you give UUGallery a look. It has some nice features.
