Protip: any original filename like 61296117_p0.jpg is probably from Pixiv, and the corresponding URL is http://www.pixiv.net/member_illust.php?mode=medium&illust_id=61296117 - same first number. _p0, _p1, etc. are the page numbers for "manga" submissions.

So here's a few artists' pages for recent posts:
