You can use the plugin not only for 360 product view. As idea for renting homes, you can make the camera to be set at the focal point instead of the object and you can spin around and view the room that you are in.
no at all. It's possible to use images from local folder, I'll add an example. You may not need to use Cloudimage token if you don't need responsive features (or you can make it yourself or use any other service). Only responsive features require Cloudimage token. However, it's great to use Cloudimage service as you can forget about resizing and compressing images for all devices or different screen width.
