Attention for people who collect from different sources and mash it together.
This clip has a slightly different number than the official number in the author provided files.
While it is listed as page/element 951 here (like in the e-hentai gallery) in the original files from Kizaru it has the number 947.1 .
So if you follow Kizarus official number scheme for your local files and you'd add this file without regarding the enumeration with the number 951, at latest when you add the next batch of pictures it will be displayed someplace in the next chapter, which could result in confusion when reading.
The guy who curates the e-hentai gallery has some offset in the pagenumbers, therefore it could become confusing.
