Images sourced from Nico Nico Seiga seem to be turning up a lot more lately. Looking at the URL's, maybe we should have a redirect like with Pixiv links? For example
the direct image link:
http://lohas.nicoseiga.jp/priv/XXXXX?e=YYYYY&h=ZZZZZ
would redirect to:
http://seiga.nicovideo.jp/seiga/imXXXXX
Doesn't seem like there's any way to tell the artist from the link like with Pixiv, unfortunately. EDIT: And because of that, it's a good idea to tag the artist and add the specific http://seiga.nicovideo.jp/user/illust/##### link to the artist's wiki for easy access.
