The code
There's a lot of PHP code to encode and decode files. Google it ➠ php image steganography
This article uses very simple code I found here ➠ Image Steganography
This page uses a ➠ simple text file and an image to combine the two into a new image.
It then decodes that image to extract the hidden text.
