    Back in time, used to hide documents inside images just using WinRAR.

    1. Create a folder called “secret”. Put the things to hide inside.
    2. Next to the folder, put an image called “a.jpg”.
    3. ZIP both the image and the folder without compression.
    4. Change the extension from .zip to .jpg.

    This probably doesnt work when uploading the image to Twitter or compressing it in general, but i was a happy 13yo kid hiding stuff in the computer.

      A very interesting topic everyone should play around with!
