[Plugin: Slideshow] Navigation arrow overlaps with text. How to fix?

Hello,

I need some help with the navigation arrows.
They tend to overlap the text, making it harder to read.

I made a screenshot as an example: http://nl.tinypic.com/r/15reekz/5

I know you can use margins in CSS to move the text to the left, but I haven’t been succesful

Any Help is appreciated.
