Firstly, you need photoshop to do this.
Secondly, download this image:
Now do this:
PNG ==> mp3
Open the PNG in photoshop
Save as Photoshop RAW
Rename .raw to .mp3
And the reverse:
mp3 ==> PNG
Take any mp3 and rename it from .mp3 to .raw (.m4a works too).
Open the .raw in photoshop (The dimensions are length x height = # of bytes (photoshop tells you the byte amt.). It might fill it in by itself. If it doesn't here's a prime factor calculator:

PS: If the one I uploaded doesn't work in your favorite music player, try the .m4a extention instead of .mp3
