Send email with picture attachment and body using google script

Question

Hi im having trouble in sending email with image attachment. because the image file name is randomized and have no way to find out if the body of my message fits the image i

To attach a file, you use File.getBlob() to attach it as a blob. For example:

attachments: [picture1.next().getBlob(),picture2.next().getBlob()]

If you know the exact id of a file (e.g. '0BxDqyd_bUCmvN1E3N0dQOWgycEF'), you can get it as a blob like this:

var picture3Blob = DriveApp.getFileById('0BxDqyd_bUCmvN1E3N0dQOWgycEF').getBlob();

Here's a working example:

function sendPics() {
  var picture1 = DriveApp.getFileById('0BxDqyd_bUCmvN1E3N0dQOWgycFE'); //public with link
  var picture2 = DriveApp.getFileById('0BxDqyd_bUCmvTFNjRkRXbXA2Tms'); //public with link
   MailApp.sendEmail({
     to: 'testa@example.com, testb@example.com', 
     subject: "This is a test", 
     body:"Test message",
     attachments: [picture1.getBlob(), picture2.getBlob()]
  });
}

and here's an example of the pictures being added inline instead of as attachments:

function sendPicsInline() {
  var picture1 = DriveApp.getFileById('0BxDqyd_bUCmvN1E3N0dQOWgycFE'); //public with link
  var picture2 = DriveApp.getFileById('0BxDqyd_bUCmvTFNjRkRXbXA2Tms'); //public with link
  var inlineImages = {};
  inlineImages[picture1.getId()] = picture1.getBlob();
  inlineImages[picture2.getId()] = picture2.getBlob();
   MailApp.sendEmail({
     to: 'testa@example.com, testb@example.com', 
     subject: "This is a test", 
     body:"Test message",
     htmlBody: 'Test message with pics inline <br>' +
     'first:<br><img src="cid:' + picture1.getId() + '" /><br>' +
     'second:<br><img src="cid:' + picture2.getId() + '" />',
     inlineImages: inlineImages   
  });
}
