Steps:
1. Gather the file you wish to link to, and the image file, and place them in a folder. For the sake of this demonstration, I will be using C:\New FolderNote:
- The image will hereby be referred to in all examples as fluffy.jpg
- The file will hereby be referred to in all examples as New Text Document.txt.Literally any file can be added. Whatever type be it.
2. Add the file/files you will be storing into the image into a WinRar type i.e. .rar or .zip. From here on this will be referred to as (secret.rar or secret.zip)
3. Open command prompt by going to Start -> Run -> cmd (if on XP) or, Start->cmd->(rt. click and run as administrator)(if on Win 7 or 8)
4. In Command Prompt, navigate to the folder where your two files are by typing
cd location [eg: cd C:\New Folder]
5. Type "copy /b fluffy.jpg + secret.rar fluffy.jpg"
