I am not posting an example code because mine is too long and
application specific. But roughly the idea of my approach is to send a
document like:

<pre>Hello</pre>
<img src="0123019230.gif">
<img src="09090909123.jpg">

and to write the two image files on a disk or in a database (which can
be kept in memory. The browser will issue requests for the two images
to your webserver which must be intelligent enough to serve them -
from a disk file or from a database. For this, you need customizable
web server - I used threaded version of BaseHTTPServer with 
a request handler from CGIHTTPServer. I use a timer to delete the
temporary files after certain delay. 

Hope this helps
