Thanks a lot!
You need to have two controller methods. One that like above creates an image, and returns the raw data (no templating, no nothing). I don't know out of my head how to do that, but I guess pylons docs will have an example. And then you create a page that contains <img src="/testfigure"/> You can *not* return a HTML-page with an image directly embedded! That's simply not supported by HTML itself.
