I use PBase for my galleries. Over4000 images are arranged in easy to find categories. When you open the main gallery you see six regional galleries plus a Fine Art Sales Gallery which contains an assortment of photos chosen for their appearance when mounted and hung on the wall.
Five of the other six open directly into sub-galleries of bird types. The North American gallery is the most extensive and is broken down into 2004-2008, 2009, 2010 and 2011. Each of these contain sub-galleries arranged by bird type.
