I would like to implement the krpano maps example ( https://krpano.com/viewsource.html?relea…s/maps/maps.xml ).

Clearly, there must be more code than this, but I don't know where to find it.

A few questions:
1) Is the ArcGIS interface free and open to the public? It appears so since the link from the code works fine straight into the browser and returns a map:
https://server.arcgisonline.com/ArcGIS/r…/tile/4/5/5.jpg
Is there any licensing concerns I should know about and do I need to sign up on their website?

2) In regards to understanding the code, a good start is to figure out where " z, y , x " variables used in the ArcGIS link are set. I can't find any initialization.

3) Possibly I need to upgrade my krpano software. I am currently using krpano 1.20.9. Is there a map function that I need to be able to call? Possibly, I need a map plugin, but I didn't see any imported in the example code.

Thanks for any help.
