This the simplest in steganography form (but without any advance protection such as password). But, very tricky way.. 
How to doing this?
In Windows:
1. Gather the file you wish to bind, and the image file, and place them in a folder. For example I will be using D:\Celly The image we will be using an example will be mylove.jpg
2. Add the file/files you will be injecting into the image into a WinRar .rar or .zip. From here on this will be referred to as (truelove.rar)
3. Open command prompt by going to Start > Run > cmd
4. In Command Prompt, navigate to the folder where your two files are by typing cd D:\Celly
5. Type copy /b mylove.jpg + truelove.rar ourlove.jpg
In Linux:
I assume that you have understand about path system. Then, just type cat mylove.jpeg truelove.rar > ourlove.jpeg
In order to view/extract your file
In Windows:
1 Change the file extension from ourlove.jpg to ourlove.rar, then open and your file is there
2. Leave the file extension as is, right click, open with WinRar and your file is there..
In Linux:
Simply type this: unrar e ourlove.jpeg
