Recap: the thumbnails on the PW "grid view" fit in 1x1.5".
Your code was:
img.thumbnail((330, 330), Image.ANTIALIAS)
That produced images 330 px high.
For PW1/2 @ 220 ppi, that gave a thumb of 1.5" high; filling the slot. But for PW3, 300 ppi, 1.1", only 3/4 size.
So for PW 3, change to (
450,450) and you get full-size thumbs.
Which I tried and it does work.
Maybe you can add a GUI setting for this.
Or default to 450, since it seems the Kindle will downscale if the thumb is too large.
Odd that all the Kindle screens are 4:3 ratio, but the thumbnails are 3:2. So unless you are incredibly fussy and redesign the thumb, one or the other will have whitespace around.
