I assume you realize that jpeg is a lossy format and that consecutively
resizing the same image will no doubt end poorly in image quality.

Also, I assume that you have a better understanding of the NEAREST and
BICUBIC options than I do because you are apparently comparing them. I do
know that those will affect your image quality.

I do not doubt that somewhere in the documentation for PIL (it can be an old
copy) that it will tell you how to set the compression level for jpeg
images, particularly when you save them back, possibly a default

Kinda shooting in the dark.
