Hiding text within an image file is one of the tricks used in Steganography. Using this trick you can hide any text information or a message within an image file irrespective of the fact that how long your information or message is. So, lets see how to do it. Follow the steps below.

Steps

Choose an image file. For example: XXX.jpg

Place this image in one of the drives in your computer system (running on Windows operating system only). Lets say you place it in \:D drive.

Open command prompt. (Press Windows+R, type 'cmd' and press 'Enter' key)

Type following command: cd.. and press 'Enter' key. Repeat this step until you left with C:\> on your command prompt window. See this image:

Now, type D: and press 'Enter' key. See this image: Now, your command prompt is able to locate D: drive.

Type following command very carefully: echo "Type your message here" >> "XXX.jpg" and press 'Enter' key. Do mind the spaces given and braces I put in the command. See this image:

If everything went perfect, Your text has been hidden within the image file XXX.jpg.

In order to see the hidden text, Right-click 'XXX.jpg' image file and open it with 'Notepad'. You'll see something like shown in this image: This is actually your image information in encrypted form. You've nothing to do with this.
