I'm supposing that Danbooru does some method of translating the "raw" or "direct" source link of a Pixiv image into the regular page link when you actually click on it.
For instance, post #807105 has http://img15.pixiv.net/img/nitrounknown/5352980.jpg listed as its source, whereas you're directed to http://www.pixiv.net/member_illust.php?mode=medium&illust_id=5352980 when you click on it.
However, this seems to be broken for images inside one of those manga-reading style Pixiv pools. post #810422 is sourced at http://img21.pixiv.net/img/zyend/15275085_big_p0.jpg but clicking on it takes you to an invalid URL. If you go to http://www.pixiv.net/member_illust.php?mode=manga&illust_id=15275085&type=scroll manually, you can find it.
Should images in these types of Pixiv groups be source-linked to their specific image where users have to jury-rig a method of actually finding the originals (either by going to the artists page to find Pixiv tags or by copy-and-pasting the source to get the raw image) or linked to the viewing-mode page which actually contains the images?
