Answer 1

importing all PIL things directly from PIL should always work. However, if you mix imports, as such,

from PIL import Image
import ImageDraw

This can lead to conflict between two un-identical PIL libraries. This can happen if you have installed both PIL and Pillow

We should really always do,

from PIL import Image
from PIL import ImageDraw
etc.

I.e. be specific about which package to use.

Answer 2

In my case it solved the situation to also import ImageDraw from PIL

from PIL import ImageDraw

Answer 3

Also happens for me on OSX 10.6.8, Python 2.6.5. I think some class is getting dynamically imported twice.

Try changing

from PIL import Image, ImageFont

to

import Image, ImageFont

That worked for me.
