How to keep Thunderbird (Linux) from displaying photos from GPG keys?

Question

Thunderbird 17.0.7 on Fedora Linux

I have the Enigmail plugin installed. Whenever I open a message that was GPG signed by someone whose GPG key includes an image, Thunderbird automatically pops up a new eog application to display the image.

How can I tell Thunderbird/Enigmail not to do this by default?

Answer 1

Open the file ~/.gnupg/gpg.conf and make sure the following entries are commented out:

list-options show-photos
verify-options show-photos

I think the last one is actually what you're searching for. Do note that this setting has nothing to do with Thunderbird/Enigmail, it will change the default behavior system wide.
