Thunderbird 2: Display Images

Yet another cool feature in TB2:
When an incoming mail contains images on the web (i.e. images not embedded into the message but rather on any arbitrary web site) Thunderbird in previous version as well as in v2.0 blocks the images per default.
This is to protect the end user from inadvertently and unknowingly sending information to malign websites.
Only if you deliberately click on "Load Images" those images will be loaded.

Now TB2 comes with an additional feature which looks like this:

The upper part has always been there, whats new is the
"Click here to always load remote iamges from some-mail-address".
If you click it, you will never see this message again for this very sender... instead images will always be loaded for mails from this sender, because you trust him, and declare your trust within Thunderbird.

This info is actually saved in the address book entry of the user.
You'll notice a new field there:
"Allow remote images in HTML mail."
This will be set by clicking on the above link. Obviously you can also do so manually...

I wonder if I want this option on a domain level... I guess not.
