Who would think there is something hidden in a picture?

Step 1: Preparations

Create a folder in any name in any directory. For this example, i created a folder named SampleFolder in C:\. Put the file/files and the picture that will hide the files.

Step 2: Main Step (zipping and Cmd Copying)

Use any file compressor like WinRar, WinZip or 7-zip. Compress it in any format (.zip, .7z, .rar). Then go to start, then run. Type cmd then hit enter. Do you know how to go through folders in cmd? To go back type cd.. then enter. To go to the folder type cd [name of the folder]. You need to open the folder where you put your picture and files to hide. In my example i started on C:\Documents and Settings\[user]>. So type ..

|------------------------------------------------------------------------------------------------------------------|
|C:\WINDOWS\system32\cmd.exe .|
|------------------------------------------------------------------------------------------------------------------|
|C:\Documents and Settings\[user]>cd .. {ENTER} |
| |
|C:\Documents and Settings>cd.. {ENTER} |
| |
|C:\>"cd SampleFolder {ENTER} |
|(your now in C:\, so all you need to do is to go to the SampleFolder) |
| |
|C:/SampleFolder> |

Once your in the folder type it in this format:

copy /b [name of the picture with extension (jpg,png)].extension + [name of the archive (.7z, .rar, .zip)].archive extension [name of the output picture].extension

so in my example it would be ....

copy /b 1.jpg + 2.7z picture.jpg

you should get the result

1.JPG
2.7z

1 File<s> copied.

Step 3: Opening the File

To open the file, right click on the picture, choose open with, and choose what you used before to compress the file(WinRar, 7-zip, WinZip). If it is not there, click choose program, scroll down and it should be there on the other programs.
