OK, done. I had to do some unexpected bug fixes and I re-arranged it so there's a folder per book, with its images and CSS contained in that folder.
I've uploaded to Mixtape.moe because Endchan fails me: https://my.mixtape.moe/xiqhwb.zip

You can rename it to "LCL_Diodorus-Siculus_Library-of-History.zip" or something.
