I am not familiar with shanachan, but it seems to use wakaba? If wakaba has an API, I can plug into it fine, but I could not find one.
Luckily, my generic 'parse the images you can see from this url' downloader seems to parse shanachan threads no prob. Go download->new url download page and put the thread url in–that should work. Let me know if it doesn't!

My dumper is old code that I haven't touched in a long time and has hence broken. It will be disabled in tomorrow's release, and when I bring it back up, it will better support dumping to arbitrary imageboards, not just 4chan.
