Some pictures not rendering in the ticket


  • Used Zammad version: 6.2
  • Used Zammad installation type: Docker
  • Operating system: CentOS
  • Browser + version: Chrome, latest version as of submission date

Expected behavior:

  • All images embedded in email attachments should render correctly within tickets, without any 404 errors or broken image links.

Actual behavior:

  • In some tickets, images that are supposed to be displayed within the email content are not rendering correctly. Instead of the image, a 404 error is shown, indicating the image cannot be found or is not being served correctly by Zammad.

Steps to reproduce the behavior:

    1. Open a ticket with an email that contains embedded images.
    1. Observe that some images render correctly while others show a 404 error in place of the image.
    1. The issue does not occur consistently across all emails, as some emails display images without any issues.

Attachments: Please refer to the attached screenshots for a visual representation of the issue. The first screenshot shows how the email with images is displayed in an alternative email client, where images are rendered correctly. The second screenshot demonstrates the issue within Zammad, where the images are not rendered and a 404 error is displayed instead.

Hi @Nuri. I cannot reproduce this issue at all, works fine here. Could you provide the mail you’ve used as EML file?

Hello, I added the eml file on mediafire (I can only upload pictures) and edited the OP to add the link

I removed the link again to avoid publishing sensitive data… :slight_smile:

I will take a look into it later this week.

Thank you very much :smiley:
