Well, I just found something! The first link to The Digimon ScreenShot Archive doesn't work. At all. So I can't help there but I'm leaving it because it's the credit that counts. And also, J-Chans Kawaii Anime Character Shrine, that seems to be gone or something too. Also, Izzy's Prodigious Screencaps has closed down....So no links here.
Yeehaw! Ryo-Ohki246 was kind enough to donate the following screenshots to ATII...Take em and die!
