Is that image not just resolved once, while posting? I remember Apple solving it in a similar way for iMessage - the sender always generates the preview.
Even if I direct link an image on discord, it essentially just rehosts that image on their CDN and displays it from there. Discord even allows that cached image to be hotlinked on any site. I have seen people use it like an image host for things like their "signature" on forums.
