I'm pretty sure you can only include one or the other in the
response, each element being treated as a separate request. Hm, well,
okay, I take that back, I know HTTP1.1 addresses the overhead of
opening separate request connections for each element, allowing the
browser to request all of the elements in one connection, but I don't
know if there's any way to take advantage of that from a servlet (if
so, it would be the equivalent of generating a jar file on the fly to
answer the request).

Or you could generate the image and store the binary data in the
session object. This amounts to being the same thing, except it would
avoid writing the temporary image to disk.
