Hide Data Inside an Image

Some of my buddies were asking me about the methods of hiding the data without making use of any type of third party paid applications. Using a professional security tool easily show that you have something important stuff or something else (you better know what i mean :D ) on hard disk that you are hiding from them. So today I am going to tell you how to hide data behind an image!

You can actually hide any type of file inside of an image file, including txt, exe, mp3, avi, or whatever else. You can actually store many files inside of single JPG image file! This is useful if you need to hide files and don’t bother about encryption and all that other technical stuff.
