In need of Mozilla Thunderbird extension

[Adde]

Anyone know of a Mozilla Thunderbird extension with the same functionality as Gmail when handling images in mail? That is, in Gmail I can choose "Always show images from this sender", but in Thunderbird I have to choose "Show images" every time since there is no "Always show..." option.

I don't want to turn this feature off in the settings, I just want to bypass it for some senders.

Does this extension exist?
