Other macro appears to be working, except for the images macro. The problem seems to be affecting all projects in JIRA, and is reproducible across different browser type. There's no related error can be found in JIRA logs file when the behavior occurs.
Diagnosis
First, ensure that the problem is not related to field renderer. The renderer configuration can be checked by going to Administration > Field Configurations > select the field configuration relevant to the affected project > go to the field, select the Renderers operation. Ensure that the affected field renderer is configured to Wiki Style Renderer.
Cause
The root cause of this behavior is because of the Internet Explorer MIME Sniffing Security Hole Workaround Policy in the General Configuration.
Resolution
- Go to Administration > System > General Configuration
Check the Internet Explorer MIME Sniffing Hole Workaround Policy configuration
Change the setting to Work around Internet Explorer security hole
