With the image display option, I don't think the "always show images from" option is not working. For instance, I will get an e-mail and click on this. The images are displayed. What I thought should happen is that next time I get an e-mail from this person, the images will be displayed. That way I can allow certain images without having to add them to my address book.
Under settings/display settings the option "Display remote inline images" is set to "from known senders".
Is this the correct operation? Always show images from seems like it should override the setting.
