I've been asked a number of times about how one views 3D models and how to show 3D models on the Internet. There are a number of free applications to create, manipulate and view any number of 3D file formats. http://www.blender.org/cms/Home.2.0.html is a very versatile application to create your own images and 3D models. there are many more applications this is just one.
