I did a quick test and while I didn't implement the full protocol, it
certainly seems possible to register a temporary handler from within a
WinForms application even if you are running as a regular user.

I'm not 100% sure but I don't believe that this is necessary if you are
registering a temporary protocol handler for your own process.

That's a good point but, afaik, it would require access to the registry
with administrative privileges to be set up.
And it seems the target user of this app could not have those privileges
granted. Or I'm wrong here, Eyvind?

How about implementing an asynchronous pluggable protocol [1]? This
is what
is used to implement the res:// protocol except that in your case,
instead
of retrieving your resource from your executable, you can do it from a
database. The images could then be displayed by using an appropriate url
with a scheme corresponding to your protocol. For example,
<img src="dbimg://...">

We did, actually, at one pint host Cassini within our application,
but it
was later removed due to security and maintenance concerns.
