popen() returns a file handle, so the following might work:

    ppm = Image.open(popen(...))

if not, wrap the image in a StringIO object:

    import StringIO
    data = popen(...).read()
    ppm = Image.open(StringIO.StringIO(data))

also see the fromstring() and frombuffer() functions in the Image
module docs.
