I saw on a video on YouTube that an image was hidden inside an image. Not the steganographically way but, opening the image on 7zip or other software and a picture file or any other file inside the original image.

Does anyone know how this was achieved? Thanks.

What I have tried:

Opening the file in 7zip but getting an error like "this is not a compressed file" or something like that
