Before I will assign it to you @neutr0nStar can you explain the project to me (show me you approach )

The below snippet is from my main.py file explaining my approach

Python GUI image steganography made by Sneharsh Belsare (Github: neutr0nStar)
libraries required: stegano, tkinter (requirements.txt available)
note: using a virtual environtment is recommended
How does steganography work ?
Each character is represented using 8 bits (1 byte) ascii code (eg 01100101)
Each pixel is represented with it's red, green and blue value (0 - 255)
We encode 1 character (8 bit) in 3 pixels,
to do so, we change the r, g, b value of each pixel (if necessary)
to either even or odd dependeing on a bit of character
0 - make it even
1 - make it odd
and the 9th value (of third pixel, blue) will be 0, if there is more data, else 1 (eof)
Eg:
character 'a': ascii value 97, binary : 01100001
3 pixelf from image: (26, 63, 164), (248, 243, 194), (174, 246, 250), (148, 95, 231)
after modification: (26, 63, 163), (248, 244, 194), (174, 246, 250), (148, 96, 231)
'a': 0 1 1 0 0 0 0 0 0 0 0 1
