I tried to rearrange the pages as good as I could (there are illustration numbers but not everywhere) so if you see something wrong please let me know.
To lurkers that might not understand what the uploader is doing: Imagine the pages are being printed as a softcover folio book. Image one is the cover in a book opened and read in standard Japanese approach. The 2nd image thus appears on the backside of the front cover and image 3 appears opposite of that page. As you see, image 2 and 3 are compatible with their details and colors at the spine of the book. Continue the same pattern and you then end up with the last image on the back cover.
Whether or not this gallery can force the previously uploaded gallery to be expunged is a different matter. The rules for a superior version to expunge a previously uploaded version are: https://ehwiki.org/wiki/Expunging#Superior As seen above, the differences are only with the inside contents and rear cover. The other uploader tried to match page details visually when viewed outside of a printed format, so there are pairs of pages properly adjacent to each other there as well. However, that gallery's uploader did mess up because his pages 12 & 18 should be adjacent to each other, page 15 & 16 should be moved to the end, and page 17 should be at the very end. In that sense, your gallery is "superior" arrangement-wise.
I tried to arrange the pages as you are supposed to read them. Japanese book are being read from right to left, it means for an full 2-pages illustrations you start with the right part. Unfortunately it breaks the picture arrangement when you read from left to right (western style, obviously image viewer ordering used in this place).
Apart from that, pages 1 to 9 were totally in the wrong place (missing leading order in the old gallery). If that part of the ordering was correct, I would not have been bothered to repost it.
