Disembowelment is for all your intestine and spleen-related gore art. This includes any organ below the ribcage.
Heartless If that heart isn't in your character's chest, or maybe just your ribcage is showing, your art goes in this folder!
Blood Smears Blood is considered gore in my book, so bring it on! A little scratch or a huge puddle, it doesn't matter!
Vomit For images of barfing blood or if what's supposed to be inside is hanging out of your character's mouth, it belongs here.
Flesh Wounds for the usually smaller, maybe less bloody gore. Scrapes, claw marks, hanging skin and such like that
Amputation/Decapitation if your character is missing a limb or maybe even their head, this folder is for them.
Impalement is for your poor critters that might have slipped, fell and... ended up with a pole in their chest? Whoops.
Nosebleeds. Did you break your nose? Here, this folder is for you.
If you have an image that includes two or more of the above, feel free to just pick your favorite folder that applies and drop it on in!
