if you embed an image from a discord link, that picture will vanish in time, that's what all that ?ex=0f18fd4c&is=0f18fd4c&hm=da4b9237bacccdf19c0760cab7aec4a8359010b023d22c4e7fc62edfdea86a0e crap on the url does: it ties it to a very specific place it was supposed to be seen, and for a limited time
you may want to copy/paste your pictures into the post itself
and if you don't like how it lays them out at the top when you do that, you can save draft then just embed the images like you were with the discord link if you really want?
