Firestorm Viewer – The Phoenix Firestorm Project Inc. – Firestorm is to Virtual Worlds what Firefox and Google Chrome are to the Internet. We develop and distribute an open source viewer for accessing Virtual Worlds. This is the viewer I find easiest to navigate second life but there are many this is my personal preference.
Black Dragon Viewer (niranv-sl.blogspot.com) This is the viewer I use for Photographs, there are many post processing features and all pose features not available on firestorm or other viewers. Also u can 360 rotate the camera on your screen which is especially great for full length or portrait photos.
