I cannot view VRML images outside Package Designer Suite. Why is that?

Within Package Designer Suite, VRML images are viewed fine. If you cannot view such images when, for example, you have exported them from Package Designer or when you are trying to open a VRML file that you have imported, most probably your system has no Cortona plug-in installed. This is a viewer that enables the visualization of VRML images. It is a small, free-of-charge program that you can download from Cortona3D's Web site.
