Hello, I'm a photographer and I've encountered that sharing through google drive is swallowing up what free storage I have. From my general knowledge, if I want to avoid a subscription, then a NAS is my best bet, but then also as far as I know I wouldn't be able to share pictures to anyone outside the network. Are there any ways to where I can say upload a file to the NAS, and then have it be accessible from anywhere with a connection similar to how Google Drive works like a link? Also, am I just not understanding how NAS's work and are they even the best option for me?
