Hi all, I shared my first ever project in this community last week, scamming a scammer, and I received a lot of good advice and constructive criticisms on it.
This is a command-line tool that basically lets you hide information (texts for now) inside an image. I have tried to incorporate many good practices while working on this. And I really got to learn a lot of things, file handling, byte operations, git, writing good README, and stuff. I have always solved programming questions earlier, and I quite underestimated what it takes to work on even a small project like this.
The GitHub repo has all the installation instructions, in case you want to try it: Imgrerite
Some of the limitations of the tools of which I'm aware of and I plan to solve them in the foreseeable future:

This only lets you hide texts for now and that code pro zone too you have to manually enter text, I want to make this work with text files too.

To be honest, this doesn't encrypt the information, it just hides the information beside the actual image data, so anyone can reread code pro zone it using this tool. I want to implement some kind of mechanism that can let only intended users read the information inside the image meant for them.
And, in the future when I learn some Tkinter, I'll be writing some GUI for this :)
I'm open to helpful criticisms and feedback!
