How can I hide files in jpeg images?

    It's a very simple trick. Just visit this link

    I actually do it with a DOS Batch file / DOS commands.

    - First, start with any standard jpg photo: my_photo.jpg
    - Then, compress (Zip) the desired document that you want to hide into a zip file to make: my_secret.zip
    -Then command:

    COPY /B my_photo.jpg+my_secret.zip my_pretty.jpg

    You end up with "my_pretty.jpg" which you can click on and it's a regular jpg photo.

    If you "unzip" the "my_pretty.jpg" you get back the document that went into my_secret.zip (Note, you may have to rename the "my_pretty.jpg" into "my_pretty.zip" for your unzipper to work).

    As a bonus, I use a password when I'm creating the zip file originally - which means that a person who casually extracts it - is still foiled with a password requirement.

    Photo display apps ignore the zip part of the resulting file - and unzippers ignore the jpg part. There's no outside indication that this resultant jpg file is anything but a photo file.

    If you have winrar installed it is as easy as renaming a picture to something.rar, then open it with winrar, drag your files and close winrar, then rename it back to jpeg.

    Chinmay, my friend, read the whole article. MobileFish helps you put files inside of images.

    Plus, MakeUseOf does have many other articles on the topic of steganography. Enjoy!
