As you haven’t posted the code, here is a simple code which correctly works
with python 2.5 on windows

from wsgiref.simple_server import make_server

def serveImage(environ, start_response):
    status = '200 OK'
    headers = [('Content-type', 'image/png')]
    start_response(status, headers)

    return open("about.png", "rb").read()

httpd = make_server('', 8000, serveImage)
httpd.serve_forever()

may be instead of “rb” you are using “r”
