Yes, you just need something like:

    response.setContentType("image/png")
    response.write(png_image_data)

Where png_image_data contains the PNG file contents. To get this from
PIL you can save your image to a StringIO buffer, eg:

    import StringIO
    buffer = StringIO.StringIO()
    image.save(buffer, "png")
    png_image_data = buffer.getvalue()
    buffer.close()

PIL is a good image library and probably what I'd use, but there are
alternatives. If you're familiar with GD you might find this binding
easier (I haven't tried it myself):

Hope this helps,
