Hi everybody, i try to send email from logstash version 7.8.0 but, images are never shown! however attachments are added to email and can be opened! i used different kind of images, none of them work ? can someone help please ```auto ruby { code => " html_table += '' html_table += '' html_table += '' event.set('html_test', html_table) " } output { email { address => "" port => 587 via => "smtp" username => "" password => "" use_tls => true authentication => "login" from => "" to => "" subject => "" htmlbody => "%{html_test}" contenttype => "text/html; charset=UTF-8" attachments => ["/tmp/files/images/na.png", "/tmp/files/images/passed.png", "/tmp/files/images/failed.png"] debug => true } } ``` ---

My understanding (acquired this morning) is that to reference an image attachment in an email you need to use the content\_id (see [here](https://stackoverflow.com/questions/922898/embedding-attached-images-in-html-emails) and [here](https://stackoverflow.com/questions/24916962/what-is-the-syntax-for-using-cidattachmentid-in-e-mail-for-image-file-used-in-c)). The Ruby mail code appears to set the content\_id to '' (see [here](https://github.com/mikel/mail/blob/d1d65b370b109b98e673a934e8b70a0c1f58cc59/lib/mail/part.rb#L14), the hash in the caller never has :content\_id set). Check the mail that is sent. What are the content\_id headers on each attachment? If they are set, then reference them in cid: URIs when trying to embed them. I suspect they will not be set (the assumption being that they are only of use if the sender knows them, so they have to set them). I do not see any way for the use of the email output to set them, so referencing images in attachments may not be supported. ---

Review the email that is sent and see what the content\_id header on each attachment is. ---

> [@Badger](#): > > content\_id header on each attachment is I did not get excplicity CONTENT-ID but something like this : ```auto MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="--==_mimepart_67978e0d733f8_1e21e808-3de"; charset="UTF-8" Content-Transfer-Encoding: 7bit ``` ---

If there is no content\_id header then, as far as I understand it, you cannot reference it in a cid: URI, and cannot embed an attachment in the email. ---

The email output will send email, but does not support displaying an image attachment embedded in the email. ---
