There are two ways of adding images to your email signature, in Thunderbird:
One method is to use the HTML img tag to show an image hosted elsewhere.
But this method has the disadvantage that email clients sometimes block loading resources called from external URLs.
The second method, which does not have this problem, is by embedding a base64 encoded version of the image into the HTML body itself, and then using this single HTML file as your email signature.
