Image Show GK4 - Sporter template

Hello,

I installed the "Image show GK4" Module. I want to place the images like it is on the sporter demo site.
But finally I get space between border and image. On the demo site there is no space. Where can I change this? Are there any class settings I must change?

This is a screenshot, so you can better understand what I want to explain in my broken english:
