For thumbnails : large images per [columns and rows] ...
[The key difference between columns and rows is that a column arranges data vertically from top to bottom,
while a row arranges data horizontally from left to right.
ex : 3x3 = 9, 3x4/[4x3] = 12, 4x4 = 16 are acceptable ... Unfortunately text details below are too small ... 

However : small images per [columns and rows]
ex : 3x9 = 27 [2x] are so lame and obvious ... sometimes they use all available squares ??? [large/small] What's the point ...


This has been discussed here [many times] ...

In addition a 137 GB of torrents will devastate and or ruin your ratio if you're not aware on these ...
There's no point of downloading huge amount of bogus torrent w/o proper descriptions and source details ...
Unless you can get a refund ...
