As you may know, image blocking defeats the “hits” spammers receive whenever one of their images is “viewed” – which can include the moment you select a spam message before you click Spam. Here’s how to block images:

1. Click Options in the upper-right corner of your Mail page.
2. From the list on the left, click Spam.
3. In the “SpamGuard” section, find “Incoming Images”.
4. Select “Initially block all images”. You’ll have the opportunity to un-block any images you’d like to see in any of your emails, but will be protected from spammers by this precaution.
5. Above the options area, click Save Changes.

You have other options, which you’ll see in this list – to show all images, or to show images only from your contacts and from certified senders.

Also, with “Initially block all images” activated, you can still selectively turn ON images on an email-by-email basis by clicking Show Images at the top of any message that contains images.

All images in messages in your Spam folder are automatically blocked.
