This is a very simple trick which requires no special software,can be done in any OS and you can hide any file such as , music,video , topsecret document in a image and mail it, upload as a image, and your file would always be safe.
You can also add password to archive file(.zip stuff) to add extra security layer.


Step 1: Creating files

Hide files in image Linux/windows

For windows users
First step is to download 7-zip and install it.

Linux
(Note:My instructions are specific for ubuntu and if you are not a ubuntu user i think you are smart enough to adapt it)
you can download it but I don't prefer it.

now make a specific folder and paste in it a image(only .png and .gif are tested) and files you want to hide.

For windows users
(Note:i am using folder C:\1)
select all files to be hidden Right Click and navigate to 7-zip => add to archive.. and select zip archive format
Linux
select all files to be hidden right click and select Compress.. in new dialog box give it a name and select .zip from slide down menu on the right.
and if you are not a ubuntu user i think you are smart enough to add all files to a zip archive.

Step 2: Command stuff

Note:Replace names and extensions of file in commands below as name of your file and images


Windows
press ctrl+R and write cmd then press enter.
now a in command propt write command
cd (after a space location of folder we made)
EX:-cd c:\1
since my folder is on c drive with name 1.
now write command
copy /b bot.png+1.zip nbot.jpg
here bot.png is name of image
1.zip is name of the zip file we made in step 1.
nbot.png is name for image to be created with hidden files

Linux
for ubuntu press ctrl+alt+T to open terminal.
write command
cd /home/ubuntu
since its the folder which has the image and zip
Now write
cat bot.png ubuntu.zip>>nbot.png
here bot.png is name of image
ubuntu.zip is name of the zip file we made in step 1.
nbot.png is name for image to be created with hidden files.

Common instruction
Always write name of image first then name of zip.

now you would have a image with a greater size than original.

Step 3: How to get hidden data

Windows
goto start >> all programs >> 7-zip >> 7-zip file manager
use it to locate the newly made image and just open it by double-click""
yes it's it you have your files.
Linux
You can rename your file and replace .gif/.png with .zip
and open it with your default archive manager.(this method is non techy guys)
OR
just decompress it with command line as a normal archive
