Steganography : Hide files in an Image

1.) Archive the data you want to hide in an image file, say data.rar

2.) Select the image you want to hide the data in, say image.jpg

3.) Open the command prompt and jump to the location you want to save the output image, say i want to save the output folder in E: drive, then type E: and hit enter.

4.) Type the following command,

          copy /b "selected_image.jpg" + "archived_data.rar" "output_image.jpg"

          in my case, copy /b image.jpg + data.rar output.jpg

5.) Go and check the location, you will find a image file with the name of your "output_image". Open it with Winrar to view the hidden data in the image.
