Intone and lyrics with album art;)

[Laszlo KREKACS]

Hi!

I would like to ask, how to add an albumart to intone?

Album art:
I tried to name just like the .mp3 file (except it has .jpg extension), but
it does not get displayed:
root at om-gta02 ~/Music $ ls -l /home/root/Music/
-rw-r--r--    1 root     root       103663 Sep  1 18:57 24  Lady GaGa
- Poker Face.jpg
-rw-r--r--    1 root     root      6533514 Sep  1 18:57 24  Lady GaGa
- Poker Face.mp3
root at om-gta02 ~/Music

Lyrics:
What is the fileformat of lyrics?
The same like for movies? .srt or .sub? (or even .mpsub?)

Is there a website to download tagged lyrics?
(ie, its not me how adjust the lyrics to the music)

Best regards,
 Laszlo
