[Python] Proper way to add an image file inside a PDF document generated with Reportlab on...

I'm trying to generate a PDF report using reportlab on App Engine Python.

But I don't know how to attach an image properly.

The image is static.

This is the directory tree of my project.



and this is what I do (inside 'chipas.py') to get the image:

im = Image('../static/logo.png',1*inch, 1*inch)
story.append(im)
...


The stack trace I get:
