EDIT: I replaced all the mega links with archive.org links and removed all images to reduce file size
I’m not 100% following, but if this is content that’s gone from being publicly viewable, uploading it to archive.org seems appropriate (but don’t take my word for it). Though if you do upload, it sounds like just the “part files” or just the “full files” would be enough. You could then also seed the torrent there.
The imgur links you might try uploading to ArchiveTeam’s imgur-grab project. Looking at the tracker, the archival seems currently half dead, but I’m sure they’ll get around to saving what’s left. (Unless it’s dead because imgur made it nigh impossible, which I can definitely imagine)
