2. Willingness to learn.

Steps:
1. Save the picture of choice to your desktop.

2. Make a new .rar or .zip folder on your desktop.

3. Add the files you want to hide into the .zip or .rar

4. Click start menu, run, cmd.

5. In Command Prompt type cd "desktop" with the quotation marks.

6. Now type in copy /b "filename.jpg" + foldername.rar outputfilename.jpg

( If you use .zip then: copy /b filename.jpg + foldername.zip outputfilename.jpg)

A quick info-fact:
With this technique of hiding files in a picture you can send this to anyone and they just have to rename the file extension to .zip or .rar.
With this technique the Al-Qaeda operatives were able to send info to others secretively.

PS:the size of the picture will increase as much as the added rar/zip
