| Hi Paul,
| 
| how is the susi going? ;-)
| 
| I tried <span tal:replace="structure item/tag" /> but I get the 
| following error:

You can't do this....

What you need to do is associate the image with a URL so it gets
generated when the browser processes the <img> tag.. UNLESS it's very small
in which case you can use the src="..." attribute to contain the data.

So a PIL image should be returned by a script or external method that
you can browse to. Headers such as Content-Type should be set to set the
image type.

Instead of generating the image on the call to your ZPT you form an <img
src="/some/url/that/makes/my/image?foo=bar&baz=bat"> e.g. in order to
generate the right image.
