Problem with Image Show gk4

Hello. I need help. I created in my Black and White template a slideshow of images as like as the template "Music". As a photos that I attach (for example) I created in my site five photos but if I set in "Slides per page" six, the photos aren't on te same line but there are four in the first line and two below. The effect is orrible.
I need that the photos are four in one line and if I click on the little circle on the right top corner I can view other photos. If I set in "Slides per page" four the other photos disappear even if I click on the little circle on the right corner.

I'm sorry for my poor English.

I hope you help me.

Thank's in advance.

I add a my site view!
