Public, full-size, not nearly as compressed version of https://e-hentai.org/g/737844/88195cf1ad/ Taken from http://wetblush.com/content/gallery/milly-frankensteins-boytoy
These images are barely larger than my gallery. This site down-scales images, in case you didn't know that. The full resolution resides in a download link below the picture. You're images look JUST as compressed!
Your gallery was 2.07MB, this one is 7.79MB. Your source files were downloaded off a chan thread (lol) and clearly read "do not distribute", this gallery's files were taken from their sponsored source and are marked for free distribution. Your source files were 1300X920 ~0.4MB each, these are 1500x1091 ~1.7MB each (and all the same size. not sure what you were trying to get across there).
No one is personally attacking you, like you seem to believe. I improved the gallery's presence on the site by uploading proper files, which happened to render yours obsolete as a result. This isn't a dick-measuring contest, it's a community with a reputation for organisation and, in this case, quality. If you think you've been "shown-up" or something, sorry but that's a personal problem.
