You can see the FAQ at
which explains

why you aren't able to add these characters, and

how you can get around that restriction

But it won't do you any good because even if you add something to the
header that looks like an HTML <img src=...> tag, it is in a
text/plain part of the message and will not be rendered as HTML.

See the thread containing the post at
for more on this.
