function convertImageToPDF(filename) {
  var image;
  // Is it a local file or web URL?
  if (filename.match(/^https?:\/\//i)) {
    image = UrlFetchApp.fetch(filename);

    image = DriveApp.getFilesByName(filename).next();
  // grab its bytes and base64-encode them.
  var base64 = Utilities.base64Encode(image.getBlob().getBytes());
  var html = '';
  // create a blob, convert to PDF
  var blob = Utilities.newBlob(html, MimeType.HTML).setName(filename + ".pdf");
