How do I use qnap flickr in sharing images securely?

Hey! Flickr has been my favorite in sharing and viewing images on the web. It has been very useful for my websites as well. I got a message in my email about qnap flickr nas saying that it is a very secure way of sharing copyrighted images. I tried to figure it out on my own but found it a bit complicated. Any idea how to go about it and how to handle some common errors? Any ideas will be appreciated.
