lifewire has an excellent article how to put an image into mail signatures: “Automatically Use a Picture in a Thunderbird Signature”

Turns out that someone is analyzing my Facebook account and sends me mails using names from my friends list.
If you get such a mail, don’t click on the link. It probably points to a page which infects your computer with a virus.
Right now, these mails are pretty easy to identify as fake because the email address is wrong. But you should know that the sender address in emails is just a text; neither the sending nor the receiving computer will check what is in there. A spammer can write anything into that field. If the scheme starts to fail too often, I expect to see “better” email addresses.
This means as a receiver, you should never click on links in emails. As a sender, you should never share links by email.
