..... you can't feed straight PIL images into drawImage.

Try creating an ImageReader object

from reportlab.lib.utils import ImageReader
im = ImageReader(filename)

You can get the size using im.getSize().

Decide whether you want to do PIL resizing or let PDF do it. If you want PIL to 
do stuff create an image with PIL manipulate it and then create a temporary file 
or StringIO containing the image and pass that to ImageReader.

If you allow acrobat to resize then just specify width and height to the 
drawImage call.
