[Plugin: Slideshow Gallery] don't show translucent arrows

how do I get rid of those translucent arrows which are on top of my artwork?

NOTE: if you change navigation translucency to 0, which would be the common-sense way to hide the nav arrow, the whole slideshow disappears. So you have to make it 1% which is kind of wonky. And, the nav arrows are still visible when you hover over the image. I really want to make nav arrows to go away for good, so could you add a feature to disable them?
