\externalref is a high-level command which constructs the complete
reference, anchor and all:
   <A HREF="....">.....</A>

It's not just the <IMG> which is added.
\externalref is not intended for use inside \HTMLcode 
as it generates its own HTML tagging.

Given that the external reference is independent of the current
document, so is effectively constant, then you could just use
a simple macro:

\newcommand{\martinURL}{.....URL to the external document's label....}

\HTMLcode[HREF="\martinURL",....]{A}{PGP Public Key}

Hope this helps,
