If you're noticing that email messages don't seem to display correctly in your inbox, or that there are large empty white "boxes" where you should actually see an image, there may be an easy fix. Add the sender of the email to your Safe Senders list - that way, the images will automatically download in your email.
If you're using Outlook, right-click on the message BEFORE YOU OPEN it. Select Junk>Never Block Sender. Once you do that, you'll see the images populate the message. Future messages from the same sender should automatically display the images.
