The other gallery is the same as this although the pictures are in a different order and have more compression. It is logical to say it is from the same source material because the picture sizes (ex: page 41 here, page 19 there) have identical resolutions except for the amount of compression. So the older gallery was probably a compressed version to obtain a nice even 100MB total upload size. The much smaller gallery is close in quality, but you can see the slight difference. Using #41 from here, compare it to #19 by looking at the green leaves in the upper left corner of both pictures. You will see that #41 is smooth (and blurry, bah) whereas #19 has some compression artifacts in the green leaf surface.
