Klaus,Perhaps we need a newbie section???
Anyway, looking at the examples (and the code making them work) provided in the viewer download package should be beneficial. Also read through the documentation at the link above (or here.
www.krpano.com/docu )
Use the search on this forum to try to find answers.
To use the tools, copy your license file into the same folder as the tools. Copy the equilrectangular stitched image (assuming you are using this input) and right click and paste onto the tool bat file of choice. This will create a basic xml, html page with all the basics. Then it is up to you to edit the xml to make it as you wish. You can always tweak the template files to output what you want.
When asking for help, it is often helpful to post a link so that others can view the issues and make a more informed answer. When I first started using Krpano, I was so clueless(as I had/have a very limited html/xml background). Then finally, it clicked. I still don't fancy myself a coder, I can make Krpano do what I want it to. Following the documentation (which should be updated to version 1.0.8 very soon) helps as well as this forum and examples. I am constantly amazed by what can be done with this software.
Hope this helps,
