A few years ago, I've downloaded a few chapters of Hatarakimono that came with a couple of other stuffs from the manga itself such as the manga's cover, a table of contents page, afterwords from takemoto izumi himself, etc. They even came with translation notes made by the owner of the website I downloaded them from (saved as a separate txt file though). The chapters in question are sadly only the ones that featured Ellen Fuwafuwaatama Aureus and I wasn't able to find copies of the chapters featuring the other two protagonists (though they do appear in the aforementioned other stuffs). As for where I downloaded the chapters and stuffs, sadly it seems that the website I got them from has been purged years ago, and I haven't been able to find it since.
Now for my question:
I was planning on uploading these chapters and stuff to Danbooru because I wanted to share them with everyone who are interested. But since these technically aren't online sources (the website I got them from didn't host images, just them in a zip file), is it allowed by Danbooru for me to upload them here?
