Thanks! On my cellphone not even enough of the UI was working for me to discover those URLs. I suspect a certain amount of error recovery is in order for wgetting all 2238 images. 2000 seems to be the maximum resolution available, which is under 100dpi. A few of the images seem to have been uploaded to https://commons.wikimedia.org/wiki/Category:Codex_Atlanticus.
I'm done downloading now (with a sleep of 1 second between pages), and I have 1064125470 bytes of JPEG files, a very reasonably torrentable size. I'll see if I can put together a torrent and upload to the Archive and Commons...
There are a couple of scans of a 43-page Italian edition published by Ulrico Hoepli on the Archive: https://archive.org/details/codex-atlanticus-leonardo-da-vin... https://archive.org/details/codex-atlanticus-leonardo-da-vin... but they seem to be of very poor quality.
