Ewww, why would anyone have their client configured to do that? That would be truly idiotic.

Personally, my email is text only. It drops all HTML. I prefer it this way. :)

Most clients are configured this way by default. I change it every time I switch.

Nearly everyone has their client configured to do that, because it is the default setting. Gmail makes that very easy to change, but many other clients have it buried in the menu

None of the E-mail clients I use load external images by default and I haven't had to configure that behavior myself.
