Yes, Having a package service installed on the NS is not a good idea.
I dont quiet get the issue of the other threads.
- I dont have a package server installed on the NS
- I can create images and see them in the console
If your client is connected to another task/package/deployment site server (you always need all three - just not on the NS), you have to import the image to the NS before.
- I can use the resource import tool without any issue
