Is it possible to attach attachments to a Jira Comment in JSM to user?

[Calvin]

We have an automation comment that provides information and a image, but for the life of me I can't figure out how to attach images to a comment via automation without just linking to an externally held URL.

I started attempting to use the new Customized Email feature as it allows attachments to try to email itself with an attachment before I figured might be best if I just stopped and asked.

Is the only way an outside external URL? Or potentially a "Maintenance Ticket" that just contains the attachment list?

Cheers
