cob.custom.customize.push(function (core, utils, ui) {
  const DEFINITION_REGEX = "Tick.*";
  const imgFieldMatcher = /[$](image|file)(\(.+\))?/;
  const imgRegex = /([a-z\-_0-9\/\:\.]*\.(jpg|jpeg|png|gif))/i

  core.customizeAllColumns(DEFINITION_REGEX, function (node, esDoc, fieldInfo) {
    // Match column keywords with $file or $image
    if (imgFieldMatcher.test(fieldInfo.fieldDefDescription)) {
      for (let childNode of node.childNodes) {
        if (childNode.tagName == "A") {
          const imgLink = childNode.href
          if (imgLink && imgLink.match(imgRegex)) {
            childNode.innerHTML = `<img src='${imgLink}'>`
          }
        }
