Cuz they're definitely not in the movie itself.  
I've seen the laserdisc only ending (where the 
Achika wedding cels are from), and they're not 
in there either.  Is there other stuff on the 
laserdisc as well?  The LD ending is all I could 
scrounge up on a web search.

I'm thinking they're from the windows cd-rom of 
the movie, but I'm having no luck in finding 
pics other than the cover scan.
