Thunderbird version: 153.0.3 (64-bit), Meadow, release channel, fully up to date.
I can successfully insert my local PNG into a composed HTML email, tick “Attach this image to the message,” and add a hyperlink to the image. The hyperlink works when the email is sent.
The problem occurs when trying to use this permanently as the account signature. HTML signatures I've tried either lose the image, show a broken-image icon, or fail to preserve the clickable image when used automatically.
I have also tested an HTML signature using a local file:///C:/... image reference, which produces a broken-image icon in Thunderbird.
I do not want to host the image remotely. I want the PNG embedded in the HTML/signature and sent with each email.
Can you confirm the correct method specifically for Thunderbird 153.0.3 on Windows, and whether there is a current issue with embedded/Base64 images or clickable image signatures in this version?
