This is just https://e-hentai.org/g/2601881/962aff8f3d/ with the extra white scan border cropped off. The images can be viewed in a side-by-side viewer correctly now.
Same crop was applied to all images. (Except the 1st image since it's a duplicate; I left it as a 'cover' with the border.)

You might wanna flip the page order of pages 19 and 20 as those two pages are the only ones inconsistent with the rest of the double spread pages. The original gallery has this error too.

Not sure it's worth a new gallery; if ppl want the change just post more comments & I'll do another gallery with the fix.
