How to make JPG images that can be played as music files

Question

I came across a strange image:

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.

Answer 1

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.

Answer 2

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