Hiding Files inside JPEG's / pictures

This tut is old and mostly everyone knows about it, but here it is anyways.

Ok, so here is the easiest way to hide files inside a JPEG.

1. Gather the file you wish to hide, and the image file, and place them in a folder. For the sake of this demonstration, I will be using C:\Secret
-The image will hereby be referred to in all examples as img.jpg and the finished JPEG will be something.jpg
-The file will hereby be referred to in all examples as Document.txt

2. Add the file/files you will be injecting into the image into a WinRar .rar or .zip. From here on this will be referred to as (secret.rar)

3. Open command prompt by going to Start > Run > cmd

4. In Command Prompt, navigate to the folder where your two files are by typing
cd location [ex: cd C:\Secret]

5. Type [copy /b img.jpg + secret.rar something.jpg] (minus the brackets)

Congrats, as far as anyone viewing is concerned, this file looks like a JPEG, acts like a JPEG, and is a JPEG, yet it now contains your file.

In order to view/extract your file, there are two options that you can take

a) Change the file extension from something.jpg to something.rar, then open and your file is there.
cool.gif Leave the file extension as is, right click, open with WinRar and your file is there.

Hope you learned something
