Topic: next/back thumbs arrows.

Hello Felix. I modified the size of the thumbnails to 30px instead of 65px through the file. I'm trying to use two rows of thumbnails on the bottom, but when I select this, the next/back thumbnails arrows are put below the thumbnails instead of beside them.
I'd like to maintain the auto resizing, that's why I don't want to get into the fixed layout. Is there an easy way to do this?
Or, how can i make the thumbnails resize (instead of the image) as I change the rows and columns?
