Just curious, how are images protected by login:password? The only way I know is htacess, which isn't really an easily scalable/usable feature... Many years ago, maybe 10 when I used Facebook I recall you could share a picture location with anybody regardless of login (i.e. Right click, copy image location, send over whatever), so the URL wouldn't be guessable or possible to predict, and the protection would be that you would get access to such url only when logged. I think in this context, the private network idea would only work if you are on vpn and you share urls that are only accesible vía vpn, is this a common setup for medical images? Is this expected? I wouldn't mind having a key or an image descrambler/decrypting/token but can't say the same about my grandma, my mother, my brother, my nephews...
