Hero Banner Not Showing in Campaign Email

We are having an issue and we are not sure why but the hero image in our campaign does not show in Outlook. It works in other email clients and when accessed through a browser. Has anyone seen this or have any suggestions on how to troubleshoot?

Outlook blocks a lot of pictures, and sometimes it can be very boring? Sadly, this is not related to Jackmail but to this specific email client.


I’m not a Jackmail or Outlook expert but I do know this; our old email system did not have this problem.
