Googling the artist helps some. Couldn't find this exact image, but artists occasionally post on piapro, and this would be [this artist's piapro](http://piapro.jp/my_page/?pid=haru_aki). Here's [some art from the video](http://www.pixiv.net/member_illust.php?mode=medium&illust_id=23499325) that's on the artist's pixiv.

For good measure, there's also a [blog.](http://medley2.web.fc2.com/frame.html)

Sign up for niconico douga. They tend to be pretty good on crediting all the art. If you can find the song there, the artist is usually in the tags.

I was watching the vid for Immoral Memory 〜The Lost Memory〜 earlier, (here: http://youtu.be/TLYWf2Zl4E0) and some of the art is just so gorgeous that it's a shame you can only see it in such low quality. In particular I love this image: (http://imgur.com/wndMpFN) but sadly its too low res to use as a desktop.

Do the original makers of the vids ever post the images anywhere?
