How to hide a file in a plain image?

One "hacking" type tutorial where I will show you how to hide a file (song, document, text...) in a regular picture!

For this you will need:

• An image in which you will hide some files,
• That same file,
• CMD ( an integral part of every Windows OS ).

Hide file:

So, create a folder where you will insert a picture and a document (or simply put them on the desktop).

Open CMD:

• For Win7/Vista users – open Start and type CMD and enter in the search.
• For XP users – open start, click Run and type CMD.

Now type "cd desktop" (without quotes) if you have placed the files on the desktop. If you placed them in a folder on your desktop, type "cd desktop/folder_name" (where you will replace folder_name with the name of the folder where your files are).

Now type the following command "copy /b image.jpg + song.mp3 newname.jpg" (without quotes).

image.jpg – the name of the image in which you want to hide the file (if the image has the name balloons.jpg, then enter it as such),

song.mp3 – the file we want to hide (if the file is named secret.mp3, then enter it as such).

Ok, now click Enter and in the folder where you have those two files, a new file (more precisely, an image) named newname.jpg will appear because we entered that name in the command.

File detection:

Now you can send that new picture to a friend, or transfer it to a flash drive, etc. and everyone will see only the image and will not even know that there is a hidden file in it (in our case it is a song).

How to discover that file? First, we need to configure something in Windows.

Open MyComputer and click the left ALT (on XP, that Menu is already at the top). Now click on "Tools" and "Folder options".

Click on the "View" tab and leave the box named "Hide file extensions for known file types" empty.

Now go back to the new file you received and you will see that it says "newname.jpg", change that .jpg to .mp3 and THAT'S IT! The song is here!
