If I understand the product correctly, the Photo product works by rendering
all the various sizes at the time you create the Photo instance. Therefore,
once you've created the 'Photo' the program used to create the images should
have no bearing on how fast the images appear on your Web site. In other
words, Photo doesn't create the thumbnails on the fly.

In my experience with 1024x768 images, the difference in speed between
ImageMagick and PIL is unnoticeable. I've got a pretty fast machine though.
