Cycle 2 Slider Plugin With wordpress

Hi there,

I am using the cycle2 plugin integrated into the wordpress gallery and works like a charm. What i would like it to do is when there is only 1 image to hide the controls and when more than one show them. I spoke to Mike on Github and he gave me a snippet of code and with my additional lines it doesn’t seem to work still. If anyone can spot how to resolve this i’d be grateful.

Maslap JQuery file: http://malsup.github.com/jquery.cycle2.js

Function to hide controls (this is in my header under the script links to jQuery and plugins)

$('.cycle-slideshow').on( 'cycle-initialized', function( e, opts ) {
 if ( opts.slideCount < 1 ) {
 $(".center").fadeToggle("display", "none");
 }
 });

.cycle-slideshow {
 height:400px;
 z-index:0;
}
.cycle-slideshow  img{
 width:100%;
 height:100%;
 z-index:3;
}
.center {
 display:block;
}
.center a{
 z-index:4;
 position:absolute;
 margin-top:-48px;
}
.center a:hover {
 display:block;
}
.center a#prev, .center a#next{
 position:relative;
 width:4%;
 height:60px;
 width:60px;
 margin-top:-60px;
 font-size:40px;
 text-align:center;
 color:#FFF;
}
.center a#next{
 float:right;
 background:url(images/next.png) center -2px no-repeat;
}
.center a#prev {
 float:left;
 background:url(images/prev.png) center -2px no-repeat;
}
