This is the complete image_processor.py module, allowing you to add an image containing an arbitrary piece of text. I use this to label the horizontal axis of a skills-matrix report.

Credit www.renewtek.com for paying me to do this stuff!

from django.http import HttpResponse

__root_image = Image.new("RGB", (1,1))
__sample_canvas = ImageDraw.Draw(__root_image)

def text_image(request, display_string):
    global __sample_canvas
    response = HttpResponse(mimetype="image/png")

    x, y = __sample_canvas.textsize(display_string)
    image = Image.new("RGB", (x+10, y))
    canvas = ImageDraw.Draw(image)
    canvas.text((5,0), display_string)

    image.rotate(90).save(response, "PNG")
    return response
