Hi,
I'm wondering how I can render an image from an external method without creating a permanent image object in Zope? What I have is a python script I call in my ZPT. The python script does some things, and calls an external method that returns PNG image data. If I do tal:attributes="src python:python_script()" What I get is the string containing the PNG image data, but it's not rendered.
An example of what I get is: <img src="?PNG <PAGE OF BINARY DATA>" />
Correct use would be <img src="python_script" alt="Some img" /> The *browser* will then call the image, not your ZPT code.
Any ideas? I don't really want to create a permanent image object, and I know that will work because I have used it to create thumbnail images before.
Thanks, Jason.
