I think this galley might need a page reorder, and duplicate trimming. It keeps repeating the sample scans every new page progressively with each story setting.. it's frustratingly difficult to enjoy this way. Which is a shame since it looks like a top shelf tooyama collection. =
This gallery is meant to be a full copy of the artist's Pixiv page. The filenames reflect that, for example, take the second page of the gallery (000_103879250_p0.jpg):
000 -> the most recent publication 103879250 -> publication ID, increases with time p0 -> first page of the publication
I didn't check the whole gallery page by page, but it seems the artist chose to publish the repeated pages. I have a script that can remove exact duplicates, but I don't know if this would help since some pages repeat the content with a different format. I wish I had a good solution for this...
You're free to make your own gallery with the duplicates removed. Here's the duplicates list: https://pastebin.com/NGQmwPHZ I'm not sure which ones should be kept or not, and I don't have the time to do a manual sorting of the files.
