It gives me this error:
req.sendfile(im)

TypeError: argument 1 must be string, not instance

Sendfile uses as:
req.sendfile("C:/img.jpg")
But i don't know how can i return when i use PIL before return ?

Then don't use sendfile. I don't know mod_python, but I'm pretty sure you
can output what you want somehow to the output stream. So, do that.

Or go down the easy road, create a temp-file to store the image and send
that.

image = Image.open(...)
image.thumbnail(...)
req.content_type = "image/jpeg"
image.save(req, "jpeg")
