How to save all images embedded in email in Thunderbird?

Question

In Thunderbird, how to save all images embedded (multipart/related MIME format) in email in one turn?

Answer 1

Select View > Show As/Message Body As > Plain text and all embedded content will become attachments. Now right-click on attachments pane, and select Save All

Answer 2

Another option under Debian or Ubuntu is

1. Save the mail to disk as email.eml.
2. Open up a terminal and navigate to the directory where you saved the mail to
3. sudo apt install mpack
4. munpack email.eml

Afterwards, all attached files or embedded images should be as single files in the current directory. For other linuxes, mpack should be available from the respective repository.
