The new gallery addresses are: http://www.dreamflyte.com/gallery/Concerts for concert photos, and http://www.dreamflyte.com/gallery/NaturePictures for nature photos. Eventually I will have other categories up also.
It should be easier for me to get this done now that I have a photo organization program. I really want iView Media Pro, but for now I'm using just iView Media. It lets me just dump all my photos onto my hard drive, and then I can essentially make a catalog of them with thumbnails, so I can find photos, but they don't take forever to load. This program is way faster at dealing with over 4000 photos than iPhoto was with a couple hundred!
