If you're using the Image module from PIL then im.resize(...) returns
an Image instance.
I have not used mod_python and psp, but try the following:

>>> import Image
>>> i = Image.open('server.JPG')
>>> r = i.resize((32,32))
>>> from StringIO import StringIO
>>> b = StringIO()
>>> r.save(b, 'JPEG')
>>> b.seek(0)
>>> req.write("Content-Type: image/jpeg\r\n\r\n")
>>> req.write(b.read())


There's a r.tostring(...) method but I don't see how to make that
return a JPEG stream.
