Images not very compressed
The kicad 6.0.11 unified image I downloaded appears to be compressed with zlib level 1, despite the script (as far as I can tell) explicitly specifying zlib level 9, causing the images to be far larger than necessary.

- converted with udzo, no arguments: 1560978846 bytes

- converted with ulfo, the macOS 10.15 fast compressed format: 1300178513
I see the imagekey command in the package script, but it doesn't seem to be getting used for the actual generation of images that get posted to the website
