Hi all,

I found a slider that works quite good out of the box with the exception of one thing, sizing images to their proper size instead of default to the smaller size. I will most likely need to add various widths so I hope to have it display them in their proper sizes.

Right now they all display at 137px while hiding the rest of the wider images.

I have this in my html:

<script>
$(function() {
    $(".anyClass").jCarouselLite({
        btnNext: ".next",
        btnPrev: ".prev"
    });
});
</script>
<a class="prev"><<</a>
<a class="next">>></a>
        
<div class="anyClass">
    <ul>
        
        <li><img src="images/logos/image1.jpg" alt="" width="223" height="61" ></li>
        <li><img src="images/logos/image1.jpg" alt="" width="223" height="61" ></li>
        <li><img src="images/logos/image1.jpg" alt="" width="223" height="61" ></li>
        <li><img src="images/logos/image1.jpg" alt="" width="223" height="61" ></li>
        <li><img src="images/logos/image1.jpg" alt="" width="223" height="61" ></li>
        <li><img src="images/logos/image1.jpg" alt="" width="223" height="61" ></li>
        <li><img src="images/logos/image1.jpg" alt="" width="223" height="61" ></li>
        <li><img src="images/logos/image1.jpg" alt="" width="223" height="61" ></li>
        <li><img src="images/logos/image2.jpg" alt="" width="137" height="100" ></li>
        <li><img src="images/logos/image2.jpg" alt="" width="137" height="100" ></li>
        <li><img src="images/logos/image2.jpg" alt="" width="137" height="100" ></li>
        <li><img src="images/logos/image2.jpg" alt="" width="137" height="100" ></li>
        <li><img src="images/logos/image2.jpg" alt="" width="137" height="100" ></li>
        <li><img src="images/logos/image2.jpg" alt="" width="137" height="100" ></li>
        <li><img src="images/logos/image2.jpg" alt="" width="137" height="100" ></li>
        <li><img src="images/logos/image2.jpg" alt="" width="137" height="100" ></li>
        <li><img src="images/logos/image2.jpg" alt="" width="137" height="100" ></li>
        <li><img src="images/logos/image2.jpg" alt="" width="137" height="100" ></li>
        <li><img src="images/logos/image2.jpg" alt="" width="137" height="100" ></li>
        <li><img src="images/logos/image2.jpg" alt="" width="137" height="100" ></li>
        <li><img src="images/logos/image2.jpg" alt="" width="137" height="100" ></li>
    </ul>
</div>

In the slider js:

    }, o || {});

    return this.each(function() {                           // Returns the element collection. Chainable.

        var running = false, animCss=o.vertical?"top":"left", sizeCss=o.vertical?"height":"width";

        ul.css(sizeCss, ulSize+"px").css(animCss, -(curr*liSize));

        div.css(sizeCss, divSize+"px");                     // Width of the DIV. length of visible images

        if(o.btnPrev)

Really appreciate any help on this..
