On the sheet that I maintain, the logo image url looks like this: <a href="https://imgsrv.roll20.net/?src=https://i.stack.imgur.com/CN5gs.png" rel="nofollow">https://imgsrv.roll20.net/?src=https://i.stack.imgur.com/CN5gs.png</a> Is the prefix <a href="https://imgsrv.roll20.net/?src=" rel="nofollow">https://imgsrv.roll20.net/?src=</a> still needed or is it a very old deprecated thing?
