Steganography is a method of encoding data into an image. This is program is meant to hide text inside of an image in an unobtrusive way, but larger applications of the tecniques used here can insert other files and even whole images.
Essentially this program takes text and an image, then subtracts the ascii values of each letter from pixels representing this text. The resulting image can then be shared and decoded.
The process allows storage of large amounts of text in a discrete way. Below are two identical pictures, but one has a portion of act one of Hamlett hidden in it.

Here is the same text placed onto a black image to better reflect the changes made to the picture.
