this happens because the domain where you receive emails from is in the trusted sender while the others are not.
When you open a message from domains where you don’t receive emails, you should see a bar appair and saying that images and links are not downloaded for security purposes, follow the instructions to allo the sender to be in your trusted list.
I hope this helps.
Thanks for helping so quickly. I did add the sender to my trusted list and I don’t see a bar at the top of the email. I know I have my Outlook allowing pictures to be downloaded.
