One image per slide

Hi,
I’ve installed the plugins in a text widget on the page footer.

But i’ve a problem :
-> There is only one image per slide

Here is the option i’ve put :
Size : 880 * 100
Image size : 160*100
image per slide : 5
Css : .logo-img { box-shadow: none !important; }
#logo-slider-wraper { margin-left: 31px; }

Can you tell me what is wrong ?

Thanks a lot in advance
