An older Wayback machine snapshot had the images. I rsync'd the complete tutorial (12 parts with text and images); made an offline archive stripping off irrelevant parts.
The last two parts has sample code that could be downloaded but I couldn't recover them. Asked the author, he too didn't have backups, but for all the other parts the code is part of the tutorial/image, no a separate downloads, so it isn't much we're missing.
