The lists of your uploaded photos — in Your Photos and everywhere you pick a photo, including packshots, photo shoots, and videos — now load one page at a time instead of pulling your entire library at once. Large accounts open noticeably faster, and every list shows the true total, so counts such as "8 of 801" are always accurate.
Search and product filters now run across your whole library rather than only the photos currently on screen, so a matching photo on any page is always found. This brings the faster Packshots grid introduced recently to every place where you browse uploaded photos.
