instagram like app for renpy game engine

As you might have guessed, I have no idea how instagram works or looks like. That's because for some reason instagram doesn't let me register an account and without one, I can't even see past the log-in page.
But for in game purposes, these basic functionalities should suffice and it can be expanded if needed.
The code for this will be exclusive to my patreon supporters for a while before I release it on my github: https://www.patreon.com/posts/61849067
