- Gather your image and the files you wish to put into it. I have a sapnwnewbie.txt which which I will attach to secret.jpg
- Add the files you want to hide into a new RAR archive
- Open Command Prompt
- Go to the folder where your files are located.
- Type 'copy /b secret.jpg + sapnwnewbie.rar sapnwnewbie.jpg' where secret.jpg is the original picture, sapnwnewbie.rar is the file to be hidden, and sapnwnewbie.jpg is the file which contains both.
- Now try opening the file with Picture Viewer and then with WinRAR.
Here is the image file with an embedded file.
