Oh interesting, this is a bit different than what I thought you were experiencing.
So when I visit that post from my instance that doesn’t happen. https://ani.social/post/4400463
It appears slrpnk.net is using a new feature called Image Proxying Its meant to protect you from data-mining and optimizes the data used.
I’m not aware of it theres a way to shut it off per user or not. I would recommend asking slrpnk.net’s admin.
Oh wow it has a demo. I’m going to try it, looks like a modern fallout 2 kinda game.
