if, for some reason, all images in the Discord Support Forum doesn't load, you can try executing this script in the console. There's a chance of it not working -- because technologies update every time --, but you can give it a try. Have a good day!

index.js

function easyCreateElement(name, attrs = {}) {
  const el = document.createElement(name);

  for (const [k, v] of Object.entries(attrs)) {
    el.setAttribute(k, v instanceof Element ? v.getAttribute(k) : k);
  }

  return el;
}

document.querySelectorAll('img[data-src]')
  .forEach(function (el) {
    const newOne = easyCreateElement("img", {
      "class": el,
      "alt": el,
      "src": el.dataset.src
    });

    el.replaceWith(newOne);
  });
