Not sure how one song could have multiple album art.. As far as albums go the artwork is held within the tag of the MP3 so it could be easy for a 10 track album to have 10 different album art covers.
It can in iTunes..... I have multiple scans from the Album sleeves on certain songs in iTunes..... you can select which one is displayed..... I have no idea hows this transfers to the iPod.... maybe just the one you have a the main to be displayed gets transfered.

I've never known it to alter the file... so I would say all are probably transfered, and the one displaye din iTunes while playing is probably the one that will show up on the iPod.
