This example demonstrates the use of hotspot images as logo and cover for the tripod. Tilt down to see the image, which can be clicked to link to any URL. A warped hotspot image is used which is dynamically inserted into the panorama background.
Code:

<applet name="ptviewer" archive=ptviewer.jar  code=ptviewer.class width=320 height=200>
<param name=file                 value="Monument.jpg">
<param name=hotspot0   value=" x750 y730 w i'cap2.gif' q u'mailto:der@fh-furtwangen.de' ">
</applet>

This image has been remapped to equirectangular projection using Panorama Tools.
