So why is this sender *linking* to the picture instead of *inserting* it
inline with the body of their message? The security feature from SP-2
only blocks images that are LINKED to. These can be web bugs. You open
the e-mail, the image is linked (i.e., it isn't included in the e-mail),
your computer has to connect with some server and retrieve the image
file, and now that server knows 2 things: (1) The IP address of your
computer; and, (2) That your e-mail address is valid AND monitored. A
non-unique web bug might be used to count how many recipients read the
message. A unique web bug can be used to validate that their message
got received into a valid e-mail account and that you opened it. MsgTag
works similarly by borrowing the web bug trick from spammers to see when
the recipient opens a message.

The new option in SP-2 added to OE will block linked images so web bugs
are killed. Some anti-spam software will do the same; for example, the
HTML-Modify plug-in for SpamPal can strip out linked images but leave
the inline images. If you read your e-mails in plain-text mode only,
web bugs are impossible (they only work with HTML-formatted e-mails
which require retrieving the remote file when rendering the HTML
output). If you sender is attaching images ("Content-Disposition:
attachment") or inserting them within the body (via copy/paste or the
Insert->Picture menu) then you will get those images. If the sender
uses <IMG> tags to insert images using remote files that require you to
retrieve them from some server (which could be web bugs and will always
incur a performance hit on downloading your e-mails) then they get
blocked if the security option is enabled in OE.
