Most of the
19,498 images in the game are not fully assembled images (if they were, you'd need 100k+ images for the game). They are, instead, pieces which need to be posed as layers to create the final scene. With the change in display ratio from 4:3 to 16:9 - not only were the backgrounds needed expanded, but then all the pieces need to be coded for proper placement on the backgrounds. Hence, Posing.
For example, here are the 174 layered "paper doll" pieces used in v0.20.16 for Roxxy to create various poses, emotions, etc. Plus, there are 404 Roxxy character composites already made that also then need posed on backgrounds for other scenes. Also, there are 2k background images in the game (some are actually 'finished' composited scenes, but many are backgrounds for which then character layers are added to create scenes).
