How to Hide MP3s in .gif Images

Pirates, take note.

Today, I will show you how to hide mp3s inside your .gif images.

.gif images allows “application extension block” which is a section of the image that isn’t checked by an image parser. Winamp (which will play .gif files) ignores everything that isn’t an mp3 block. As a result, you get an image that looks like an image to the untrained eye, but if you drag the image to Winamp, you’ll hear sounds. Here’s how to do this:

If you don’t know what the command cd does in command prompt, put your .gif image and the mp3 file you want to embed in your c:\ drive (double click c: in My Computer and put everything there). If you know what cd does, feel free to put the image and mp3 anywhere on your computer.
Bring up the command prompt (Start -> Run… -> type cmd)
Change the default directory to the directory that your gif image and mp3 are in. Type cd c:\. If you chose to put the image and mp3 file elsewhere, change the directory to that directory.
Type copy picture.gif /b + music.mp3 /b mp3inside.gif

picture.gif is the name of your picture. music.mp3 if the file name of your mp3 file. If the file name contains spaces, put double quotes (”) around music.mp3. mp3inside.gif is the output name.
