Making Slider smaller and showing the full image

Hi,

When using the furniture slider, how can I make the slider height smaller? It’s too big for my personal preference. Also, it seems to be enlarging the image. Is there a way to show the full size?

I would like the slider to be smaller and possibly fit on the screen at first glance without having to scroll down a bit to finish viewing it. I tried playing with the padding, but it doesn’t seem to be doing anything.

The image shows almost the full size of my screen and I still can see the bottom of the slider.
