excel - 如何将图像附件发送到电子邮件

Question

因为我创建了要扫描的二维码列表，然后我想使用 Google 应用脚本将此图像发送到电子邮件。
当前结果
图片未发送到 gmail。
代码

 function sendEmail(sheetName = "emails") {
  SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheetName).activate();
  var spreedsheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var lastRow = spreedsheet.getLastRow();
  //var ssa = SpreadSheetApp().getSheetByName(sheetName);  // spread sheet object

const messageBody = "Dear receiver, We would like to invite you on upcoming seminar please use this link {actual link} and show receiptionis this bar code {actual code}"
const subjectText = "Seminar invitation"

 // loop rows or spread sheet
  for (var i=2; i<= lastRow; i++) {
    var receiverName =  spreedsheet.getRange(i, 1).getValue();
    var receiverEmail = spreedsheet.getRange(i, 2).getValue();
    var seminarLink =  spreedsheet.getRange(i, 3).getValue();
    var barcode =  spreedsheet.getRange(i, 4).getBlob();
    var msgBdy = messageBody.replace("receiver",receiverName).replace("{actual link}", seminarLink);

      var photoBlob = barcode
     MailApp.sendEmail({
                to: receiverEmail,
                subject: subjectText,
                htmlBody: messageBody + "<br /><img src='cid:qrCode'>",
                inlineImages: { qrCode: photoBlob }
        });  
 }

}

从您的以下回复中，

images are created from =IMAGE("chart.googleapis.com/…) with that google sheet excel

在这种情况下，我认为您的目标可以使用 Google Apps 脚本来实现。
当我看到你的剧本时，getValue()在循环中使用。在这种情况下，处理成本会变高。在这次修改中，也修改了这个问题。
修改后的脚本:

function sendEmail(sheetName = "emails") {
  var spreedsheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheetName);
  var lastRow = spreedsheet.getLastRow();
  const messageBody = "Dear receiver, We would like to invite you on upcoming seminar please use this link {actual link} and show receiptionis this bar code {actual code}";
  const subjectText = "Seminar invitation";
  const range = spreedsheet.getRange("A2:D" + lastRow);
  const values = range.getValues();
  const formulas = range.getFormulas();
  values.forEach(([receiverName, receiverEmail, seminarLink], i) => {
    const url = formulas[i][3].split('"')[1];
    const photoBlob = UrlFetchApp.fetch(url).getBlob();
    var msgBdy = messageBody.replace("receiver", receiverName).replace("{actual link}", seminarLink);
    MailApp.sendEmail({
      to: receiverEmail,
      subject: subjectText,
      htmlBody: messageBody + "<br /><img src='cid:qrCode'>",
      inlineImages: { qrCode: photoBlob }
    });
  });
}

运行此脚本时，将从工作表的“A2:D”中检索值。并且，从每一行中检索每个值。对于“D”列，从公式中检索 URL，并使用 UrlFetchApp 检索图像 blob。并且，这些值作为电子邮件发送。
