HTML mail is here to stay, so a client needs to handle it well. Since images in HTML mail are security problems, a good client won't load them until you say so - and should also let you white-list some senders.

GMail does this well enough, with two links - one to show the images in a message once, and another to whitelist the sender. I'd say that's about the best you can ask for. If you want to remove a sender from the whitelist, it's a little obscure - you have to find an email from them and there's a link in the details that says "Don't display from now on."

One interesting thing is that this is a separate list of addresses from your Contacts (which in GMail, includes every address in every email by default).

Thunderbird starts off with basically the same interface as GMail. They show a big loud bar that alerts you to the missing images, as if you couldn't tell. You can press a button to load it once, or click a link (why not another button?) to whitelist the sender.

This is where we go a little haywire, though - all I want to do is whitelist the sender for images, but Thunderbird throws up a sheet asking me for all kinds of contact info - now the sending email is in my address book. So I end up with a bunch of noreply addresses in a group in my address book called "Personal Address Book." Thanks?

I think a whitelist just for image display that's separate from the address book is the way to go - it seems more natural. An address book seems like something I should control manually. Ideally, in a desktop mail client on OS X, the client's address book is just the system's Address Book DB - so that other apps can use the info. And since that's system-wide data, you really don't want a client just dumping everything in there.
