Well, think about it a bit. Anytime there's an embedded image with an
IMG tage, it's handled with a separate request/response. It'll be the
same thing whether the whole page is served statically by a web server
or dynamically by a servlet.
The real question here is whether the image is going to be served by
the web server or the servlet. If by the web server, then just put an
appropriate URL in the IMG tag. If doing so, be careful of using
relative URLs, because if it's in the same directory relative to the
servlet, the request will go to the servlet, and in this case you
don't want that. If by the servlet, then you do want the request
going to the servlet, and you have to have something on the URL (like
parameters) indicating that it is an image that is to be returned, and
what image it is. And you have to have set up your servlet to handle
returning images.
I suspect that most people will want to use the former approach,
unless perhaps their images really are dynamic.
