jquery kwicks resizes my image

Question

I am trying to put image inside a kwicks ul li, and to make it's width fixed on 860px no matter if li is colapsed or not. And I just cant stop kwicks from resizing my image.

As you can see on this image, only first (expanded) li is showing my css width property 860px, but the other ones are resized. Is there a way around it?

Everything works fine if I assign background-image to each li, but I want images to dynamically change - and for some reason I cant assign css-background property vie jQuery. So now I managed to dynamicly insert img tag inside each li but I cant make it stop resizing.

Please, any suggestion would be great.

  <ul class="kwicks-category kwicks kwicks-horizontal">
 <li class="kwicks-selected slideshow1"><img width="860" src="http://localhost/nidzan/Okvir/wp-content/uploads/2014/12/Untitled-1.jpg" class="attachment-small-thumb wp-post-image" alt="Untitled-1"></li>
 <li class="slideshow2"><img width="860" src="http://localhost/nidzan/Okvir/wp-content/uploads/2014/12/Untitled-1.jpg" class="attachment-small-thumb wp-post-image" alt="Untitled-1"></li>
 <li class="slideshow3"><img width="860" src="http://localhost/nidzan/Okvir/wp-content/uploads/2014/12/Untitled-1.jpg" class="attachment-small-thumb wp-post-image" alt="Untitled-1"></li>
 <li class="slideshow4"><img width="860" src="http://localhost/nidzan/Okvir/wp-content/uploads/2014/12/Untitled-1.jpg" class="attachment-small-thumb wp-post-image" alt="Untitled-1"></li>
 </ul>

 .kwicks-category li {
  display: block;
  height: 300px;
  background: #999;
  position: relative;
  /* overridden by kwicks but good for when JavaScript is disabled */
  margin-left: 5px;
 float: left;
 }

 .kwicks-category li img {
  position: absolute;
  width: 860px;
  top: 0;
  left:0;
  }

$(function() {
    $('.kwicks-category').kwicks({
        minSize : 50,
        spacing : 5,
        behavior: 'slideshow'
    });
});

Thank you.

Answer 1

I actually found solution 15min after I posted the question.

What I did was wrap all img tags with a div and assigned it width property.

 .kwicks-category li img {  
  width: 860px; 
 }

.kwicks-category .img-wrap {
 position: absolute;
 top: 0;
 left:0;
 width: 860px;
 }

Works like a charm, all images inside li tags do not get resized and I am still able to dynamically insert images into kwicks slideshow.
