I made a Twitter bot using Tweepy and Python

This was my first time ever building an application that has a real world application, as well as my first time working with objects in Python. The project is hosted on GitHub: https://github.com/andrekato1/The-Corginator

And you can also interact with the bot on Twitter. Send a mention to @CorginatorBot with or without a message included to get a random cute Corgi picture! Yes, this is all the bot does. And in a very simple way: the pictures are all stored in my local file system. I was wondering if there is a way to dynamically and randomly get these pictures on the internet without having to save them one by one on my computer. If anyone has some pointers on how to do this, I really appreciate. Feedbacks in general are also very appreciated.
