I wonder if @[email protected] initially posted the image I see, then federation sync happened to fedia.io, then OP changed the link to a different image, and fedia.io didn't update it?
Yeah, if I do "open original URL" and go over and look at the post at lemmy.world, I see the image you are seeing.
I've noticed other federation missteps with votes, just trying to pay attention to these little weirdnesses that are emergent properties of a decentralized social media environment.
