I came across a strange image:

enter image description here

Apparently, somehow they managed to make a JPG file also play as a media file. I'd like to know what program you use to do this.

They may have used a dedicated steganography tool, but you can probably do it in a command-prompt.

  1. Open a command-prompt (Win+R -> cmd.exe -> OK)
  2. Type copy /b
  3. Drag and drop a JPG to the command-prompt window
  4. Type +
  5. Drag and drop an MP3 to the command-prompt window
  6. Type a filename (eg Combined.jpg), then press Enter

Open the new JPG in an image viewer, then in an audio player. It may or may not work depending on the viewer or player.

Why the downvote? Comments really should be mandatory. – Synetech Mar 5 '11 at 19:33

You should try google before you post. Combine JPG and MP3

-1: Kind of rude saying the person should try Google first. – Wuffers Mar 5 '11 at 4:30
Kind of true though – datatoo Mar 5 '11 at 19:20
