Images invisible

dear author,

On http://unravelled.nl/ I am using your plugin, but the images are invisble. Using Firebug in Firefox, I can see the images are rotating (somewhere), but they don’t show up. Can you see what is happening?

this is what I see in Firebug:

<ul class=”irw-slider” style=”z-index: 2; visibility: visible; margin: 0px;”>
<li class=”” style=”display: none;”>
<img width=”528″ height=”48″ src=”http://unravelled.nl/wp-content/uploads/2012/10/quote_home4.gif&#8221; style=””>

<li class=”” style=”position: relative; top: 0px; left: 0px; display: none;”>
<li class=”” style=”position: relative; top: 0px; left: 0px; display: none;”>
<li class=”” style=”position: relative; top: 0px; left: 0px; display: none;”>
<li class=”” style=”position: relative; top: 0px; left: 0px; display: none;”>
<img width=”528″ height=”48″ src=”http://unravelled.nl/wp-content/uploads/2012/10/quote_home6.gif&#8221; style=””>

<li style=”position: relative; top: 0px; left: 0px; display: list-item; opacity: 0.1275;” class=”active”>
