Just a little Python script that I wrote some time back. I originally used it to smuggle Counter-Strike cheats through the Steam community, hiding cheats inside images that I uploaded to the Steam community workshop. The script itself doesn't do much, you can do this without the script, but it is harder, all it does is make it simple for you.

Make a new folder, inside the folder you need an image, remember the file extension of the image.
Inside the folder you made, make a zip/rar file containing all the files you want to hide excluding the image.
Place stash.py inside the folder you made with the zip/rar and image.
Run the Python script, and follow the instructions.
