Paul, I've used the first two techniques you mention before; in each
case the IMG tag in the generated page specifies the URL of a resource
that the browser makes a separate request for. However I'm intrigued
by your third option, namely "sending the image with the Web page". By
this, do you mean sending back a multipart message that includes both
the HTML page and the generated image?
