steganography with image

-
Hide some information in your file,like images. This is what I do! Hope you can learn something.
First, you have to prepare a image(download from everywhere).


Build a start.bat  in the fold with the downloaded image. 
Second,  set a txt file writing something you want hide. Then zip the txt into a .rar.  
Most importantly, open the start.bat to add some words .


BINGGO! The myst.txt file which we want to hide is zipped inside the file .rar. 
Only knew by who set it. How privacy I feel!
