you  can hide your file in the picture..so no one realize there’s a file in the picture.
now i will give you the trick. but, make sure that you have WinRar on your computer.

1. Show your extention file.
   Control Panel -> Folder Option -> View ->
   uncheck in the option “Hide Extension for known file types”.
2. prepare the file that you want to hide,example video_rahasia.avi and
   one picture file example Mantaf.jpg (you can hide in *.bmp,*.jpg,*.jpeg).
   and save those file in the same directory.
3. right click on video_rahasia.avi -> [Add to “video_rahasia.rar”].
4. OPen Notepad (Start -> Run -> type Notepad). and write this script :
   

   @echo off
   ren video_rahasia.rar video_rahasia.avi.rar
   copy /b Mantaf.jpg+video_rahasia.avi.rar hasil.jpg
   del video_rahasia.avi
   del Mantaf.jpg
   del video_rahasia.avi.rar
   del hide.bat

   Save the file and give the name hide.bat

5. Double click on hide.bat, if it’s worked, all file in the folder will change into hasil.jpg

That’s all,you can open hasil.jpg in image viewer, there’s no change, except file size is bigger.

if you want to take the hidden file , just Right click on hasil.jpg -> Open With -> WinRar..
