if you're using PIL to create the image, you can (usually) save the
image to the response object, e.g.
response = HttpResponse(mimetype="image/jpeg")
image.save(response, "JPEG")
the response object doesn't provide the full file API, so some less
commonly used file format drivers may fail when doing this (usually
because they need "seek"). common web formats work fine, though.
if you want to support more than one format, you can use PIL's MIME-type
registry to simplify things a bit:
from PIL import Image
Image.init() # explicitly load available file format drivers
...
def myview(...):
format = "PNG"
response = HttpResponse(mimetype=Image.MIME[format])
image.save(response, format)
...
you may e.g. want to use "JPEG" for truecolor and grayscale images, and
"PNG" for palette and bitone images:
if image.mode == "P" or image.mode == "1":
format = "PNG"
else:
format = "JPEG"
