Got any pointers for tags I should use for stuff like genitalia, fluids, and so forth?
Yes, tagging those are good
Can anyone please give me some pointers on how to tag explicit images?
Your question is so general/nonspecific that it’s hard to begin to even say anything.
Tag the characters’ visual sexes (male/female/futa), explicit body parts that are visible, and other features that make it explicit. There are a lot of explicit images on the site and it’s not hard to find some in order to learn what those tags are.
Tag body types (pony
/anthro
/equestria girls
/human
). Tag relations (straight
for male x female, gay
for male x male, lesbian
for female x female, “futa on futa
”/“futa on male
”/“futa on female
”, canon x oc
).
Tag kinks and fetishes that are depicted.
If you miss something important, the worst that should happen is a comment asking you to tag something or other (phrased as rudely as possible, of course)
Look back at the tag changes on pictures you upload to learn new things.
