Thunderbird allows you to set 'alt' (by default, the "alternate text"
option is active, if you don't fill it, a message pops up when you
click "OK" inciting you to fill the field in, or select the "no
alternate text" option, in which case an empty alt="" is generated).
When you drag/drop an image into a message, the default is alt="".

Yes there is: the Content-Description header.
