I haven't been able to find anything online that works, but is it possible to change the size of an uploaded image on a game page in the markdown?

Pretty much just what the title is asking, I'm not quite at the point where I can make a build to test, but I don't want to waste time uploading a web build to ldjam if it's not going to work

Is there a way to set up an Itch.IO page to allow HTTP requests from an embedded game? I set up a public leaderboard system only to find that the request is blocked by itch when I uploaded my web build. (Using Godot 4 if that matters)
