Images display space

Hi,

I am using the slider for images. The pictures are not the same size, so I am using the option that resize the height automatically so they are aligned vertically. Is it possible for the slider not to display crop images on the far left and far right sides?
It is setup to display 5 images, but you can see 5.5 pictures. Hope this make sense. It would look nice to just display complete pictures without any crops.

My theme is ascension, child theme. Primer is the main theme. I have provided the url.

The slider settings are small size, auto height, arrows will move one picture at the time.

I am not sure if this is possible, but worth asking.

Thanks
