Does your software require a plug-in download for others to view the panoramas?

 Answer:

For either panoramic tours created with Panoweaver or virtual tours created with Tourweaver, plug-in should be installed to the browser (IE, Firefox or other browsers) in order to view the panorama tour and virtual tour in that browser.

Java applet panorama tour and virtual tour require Java platform (Microsoft JVM  or Sun JRE);
QuickTime panorama tour requires QuickTime Player;
Flash panorama tour and virtual tour require Flash Player 9.0.
