Unable to edit/embed cover art in aac files

Hi All,

I'm having the following problem, I'm reripping all my audio cd's to aac (HE-AAC 48kbps parametric stereo) because I'm switching from iPod to Nokia N78. I want to embed the cover art in the file as opposed to having the picture files separately (otherwise the pictures show up in my Nokia in between my own pictures). I'm using winamp to rip and trying to embed art with mp3tag but in the extended tag I cannot change the cover art, when I right-click the menu shows in light gray( not selectable). If anyone knows what to do please let me know, I have searched both this forum and online but sofar nothing! Thanks.

Adding cover art to native AAC is not possible. If you'd use AAC inside MP4 adding cover art is possible.
