Recently switched to the "new" JIRA experience in settings. In the "old" experience, you could attach an image file to a JIRA item and then in a comment there was a drop-down from which you could choose that attached image from a list and it would add a thumbnail entry to the comment text. The comment would then contain a clickable thumbnail to the attached image.
I can't seem to find where to do this in the new experience. Anyone know?
