Mail displays the message's remote images.
TIP
How do remote images cause me to receive more spam?
Many spammers include in their messages a
web bug
, which is a small and usually invis-
ible image, the code for which is inserted into the e-mail message. That code specifies a
remote address from which to download the web bug image when you open or preview the
message. However, the code also includes a reference to your e-mail address. The remote
server makes note of the fact that you received the message, which means your address
is a working one and is therefore a good target for further spam messages. By blocking re-
mote images, you also block web bugs, which means you undermine this confirmation and
so receive less spam.
