I'm sorry if this is covered elsewhere, but I swear I looked. Is there a way to add an image in the sandbox so I can get feedback on it/ask others if it's fair use? Thanks.
Upload it to Files (at the bottom of the page) just like with a page on this wiki.
Eh, I must be dumb, because I'm sure not seeing it. Thanks, though. At least I know it can be done.
Edit—Found it! Boy, I am a dolt.
