Hide Files in pictures

Hi, friends i am share simple tips for hide data in picture....It`s  save your data file from unauthorised access in a very simple manner
# You will need the following.. Windows 2000 / xp
# WinRar
1. Gather your image and the files you wish to lodge into it. Here I have a nisha.txt which I will hide inside my cloud.jpg.
2. Add the files(e.g nisha.txt) you want to hide into a new RAR archive. (in the archieve name box type nisha.txt and hit enter. Now ur file is in format nisha.txt.rar)
3. Open Command Prompt and go to the folder where your files are located, e.g., ‘C:\nisha
4. At command prompt type ‘copy /b cloud.jpg + nisha.txt.rar ritu.jpg’ (without quotes).
(cloud.jpg is the picture I want to show, nisha.txt.rar is the file to be hidden, and ritu.jpg is the file which contains both).
5. Now test the ritu.jpg by double clicking it, and verifying it still opens.
6. Now try opening that same ritu.jpg file from menu i.e right click on doc.jpg file you have created : openwith->WinRar archiever. It will show the original hidden file nisha.txt.
Now ritu.jpg is a simple JPEG for others, but it contains a secret file nisha.txt for you…
