several lines logo

Hello,
I have installed installed the logos carousel plugins however I cant find these settings in the relevant sections :
– Is it possible to display the logos on several lines? I can see we can display on one line and then go to previous/next page
– Is it possible to change the size of the logos? Currently even if I enter a different size it all goes to the same dimension
– How do we center the logos? When they are a smaller size, they go to the top of the image.
Many thanks
