Finds tiny 1x1 images used for tracking, hides them and removes their source.

Code to copy

(function () {
  document.querySelectorAll('img').forEach(function (img) {
    var w = img.width || img.naturalWidth, h = img.height || img.naturalHeight;
    var aw = img.getAttribute('width'), ah = img.getAttribute('height');
    var tiny = (w <= 2 && h <= 2) || (aw === '1' && ah === '1') ||
               (aw === '0' && ah === '0');
    if (tiny) {
      img.style.setProperty('display', 'none', 'important');
      try { img.removeAttribute('src'); } catch (e) {}
    }
  });
})();
