Hide a file in a picture
Steps
    Prepare the picture test.jpg and test file test.txt
    Use WinRAR to compress test.txt to test.rar
    Open "cmd", then cd to the directory where you store the picture and the test.rar(put them in the same directory)
    Type command : copy /b test.jpg + test.rar test.jpg, hit "Enter" key
    Ok, open the test.jpg, you will still be able to view the picture
    Where is the txt file? Open WinRAR, click "File"->"Open", select "All files", find test.jpg and open, you will find the test.txt file there.
This method is suitable for hiding all kinds of files. It's easy and secure. The picture file will still remain the same size and you can still view the picture without problems.
