How to share my photos from time capsule external drive over the internet.

I saw some article that, i can share my photos from time capsule drive over the internet. Also, heard it can be done through manual configuration of time capsule. Firstly, i do not see such option in my time capsule configuration. I did a factory reset assuming, i might have configured through auto mode for the first time (that could be the reason why i don't see manual option). Now, i don't know, how can i share my images over the internet frome time capsule drive, without using my mac book system up and running all the time.. I wanted to create a secured user id/password to let the other users to access my network share drive. Is that possible?
