Game rips containing ALL the characters from the browser game as of October 2014. If you just want the girls (and traps), there's that other gallery that was uploaded before.

Naming convention:

AABCC

AA = Arc (Up to 10 are out as of Oct 2014)
B = Chapter (Usually 4)
CC = Card number

PR (promotional cards) bend the convention but are generally categorized under their arc. Alt colors exclusive to the browser game also uses the same card number as opposed to the actual alt colored versions that were released as cards.

Fugakuden is the prequel and TCS has no story thus both are named differently.
