I'm fairly new to krpano, using it successfully to include dozens of panoramas in a family website alongside thousands of images and videos. I'm working on creating an offline version on a portable drive that is as future-proof as possible (that I can create copies of to give to my kids). Using HTML pages to present the archive, I'll keep them as vanilla as possible to avoid future problems with layout or scripting.
What is your recommendation for a future-proof way to present the panoramas?
