Edit: Replaced with proper rip, previous one used wrong profile when converting ppm to jpg (apologize for this, but the batch rip is done long time ago), this should be more closer to raw now. The difference can hardly be seen by bare eyes, you only need to re-download this gallery if you are super hardcore on quality.

bought it myself and directly ripped from:

If you have DRM free PDFs and not sure how to rip them, you can send them to me and I'll try to help.
