omg, you did? I see that you used the sliding window with 3 parts. The closest pages are left as is. Then next set use the technique #1 unloading images. Then the next set of pages use technique #2 hiding pages, while the rest of the pages use technique #3 removing pages. Why not just use #3? Is there a speed advantage to still having around the pages with the fake image and the pages with visibility hidden?
