Tip: You can also go directly to the Spam options page by clicking the Options link in a message with blocked images.

On the Spam page, select one of the blocking options for incoming images:

Always show images, except in Spam folder—When you open a message in the Spam folder, none of the images that the message contains are downloaded. Images in all other messages are automatically downloaded when you open the messages.
Show images only from my contacts and certified senders—When you open a message from someone on your contacts list or from a certified sender, the images are downloaded.
Initially block all images—When you open a message, none of the images that it contains are downloaded. This is the default setting.
Click the Save Changes button to save your settings.

When image blocking is enabled and you receive a message that contains image attachments, a message appears above the headers in the Reading Pane for that email message, informing you that the message contains blocked attachments. If you want to see the blocked images, click the Show Images button.

You can disable most image blocking at any time by repeating the steps above and then selecting the Always, except in Spam folder option.
