Others have pictures of stuff like maps, items and landscapes.
If a pic has a person, it directly goes to the 'people' foulder, no matter if it has mons or not. The People foulder has a foulder for each character and 'popular' groups of charas have one too (for example E4s, Gym Leaders, Protags and rials together, ships, etc). That is, though, if I have enough pictures of it, usually around ten.If I have less it goes to a general 'group' foulder.
Pokémon foulder has foulders for each evo family, and a foulder for each common group usually drawn together (trios, starters, etc). Like before, if something doesn't fit a category, it goes to a 'random groups' foulder.
I don't save gijinkas. Porn goes to its corresponding character foulder.
