Images not blocked by outlook

Why are images not being blocked by Outlook?

You are probably receiving emails that are almost entirely an image hocking stocks or drugs. How come that image is not being blocked??

If you view the source of the email you will notice that the image is not being called in the standard format of:
IMG SRC="http://www.sender-company.com/images/flower.jpg"

Instead you will see this:
IMG SRC="cid:My-Image-Identifier"

The difference here is cid. This is an embedded image that travels along with the email. Outlook blocks image "calls" like the first example.

How to you block these images? We'll see.
