The problem is not with import images, the problem is with file sharing. You can save files to an usb on PS4 with no problems, but you can only use these files in your profile, you can´t share with other people.
I still believe that the best solution for Konami is to create an online server to share the created data, in stead of people sharing direct through each other. That way they would not depend on Sony and M$oft.
According to this guy we can import images. Is he wrong?
