Sony E-Series Album Art

[Aleatoire]

Hi, I have a Sony E-Series MP4 player and I can't figure out how to put album art on it. Some albums on it have album art already while most don't. I don't know how the ones with art got their art but they do.
How do I put album art on it for all of my albums? No matter where I look I can't find info on how to do this.

Ok, don't worry I found a program called MP3Tag that seems to do the job.
Thanks.
