When someone send me a html-format email which usually includes some images like background picture or signature picture, etc, the thundbird can not show them in the email body in html. In contrary, it handles them as attachments with a strange file name like "D38CF7A7@FB9CB071.ADF80B60".
Since the extension file name can not be recognized by the OS, the file can not be open by default image software.
Here is an example of the email source (some content has been cut off), as well as the screen snap.
