Hi,
1) Windows or not, is that related to the client or related to the webserver?
That's only related to the krpano tools which are preparing the images. The resulting pano files (the viewer, plugins, images) are only static files and run completely on client side via HTML/Javascript and/or Flash and completely independent of the server.
2) is that simply UPLOADING files then it will work on the webserver?
Yes.
3) while preparing the files, do I need to care about the web host URL or domain names? Do I need to indicate the domain name anywhere in the license file or in the .xml / .js files?
No.
But if you want you specific a custom domain limitation in the krpano Protect tool - then the pano will only work on the given domain.
4) do we require the webserver any web application ability
No.
Best regards,
Klaus
