I dont get your question.
There are about 55k threads archived with the images.
Webm's are not archived due to their size. /gif/ as well.
If the image was delete while the thread was being archived an 404 pic is shown.
The images are there, all are hosted on imgur or imageshack to decrease load&bandwidth as well as to be a bit safer on the host side.
This was introduced because it's showing the image's actual size, not the thumbnail. I never got to reading properly imgur/imageshack's API to do that and because you dont want to go to a thread and see instantly 150 pics with lets say 1200x1200 resolution and thus your browser to become really slow or even crash, I added Lazyload.
r9k is now archived.
s4s... not yet.
I'm having atm a personal selective archiving to test out how it works and will soon add an on-demand archiving function.
As someone said this archive is not based on fuuka, it didn't automatically pull all 4chan threads based on their API, it was more of "lets see what the average users actually thought is worth archiving, so you dont end up with 5000 "post your fb/ex slut pics" threads" idea.
I do have the DB (threads and posts) from archive.moe's archive and as everybody else is waiting for the pictures. The thing is that I highly doubt that I will merge archive.moe's DB with 4chanarchives.cu.cc
's db due to numerous reasons, DB integrity to name one.
I have other plans actually for the archive.moe's DB but all in it's time.
