Firstly, ensure you have 'downloaded' the images in your inbox. Various browsers (such as IE) do not automatically download the images.
If you have downloaded the images and they are not appearing then head back to your ‘Communications’ tab and select the email that is not displaying properly. If you notice that it is because one of the image fields has not been updated you can ‘Duplicate’ the email and edit it.
If the problem persists please email us at firstname.lastname@example.org.
