[Plugin: NextGEN Gallery] [Plugin: NextGen Gallery] Force Thumbnails Rows et Columns

Hello,

I would like to force rows/columns fopr the thumbnails presentations in my post.

By exemple if i get a gallery with 9 images, i Would like 3 colums and 3 rows instead of 2 rows and 8 columns. (8 thumbs in the first row and only one in the second)

Also if i get a gallery with 15 image, have 3 rows of 5 columns.

In fact, manage it depending of my numbres of thumbnails.

Thanks a lot and sorry for my poor english.
