I know the quality looks extremely similar between them, but this one is just a tiny bit higher quality.
Edit: And since some people don't believe me, check the hashdb link: http://hashdb.com/6469e302b6e733a9669e3120175dc5f8 The size is the same as this one, and not the one this gallery is replacing. This is the correct version.
Edit:The images are better but you need to open them in some other program. To an average viewer it may not even seem like there is a difference. To notice it better Open pages in photoshop or something similar its not gonna just be evident in a browser.
