Html – Nivo Slider Jquery Plugin – images resizing automatically

QUESTION:

How can I get my pictures to not be so blown up? And why can I not see the whole image?

EXPLANATION:

I put the Nivo Slider Jquery Plugin on my webpage and it works great! The problem is when I put an image in, the image is not the right size. The image is blurry and the slider isn't showing the whole image. I looked at the CSS and it looks fine to me. Here is my HTML code:

       <div class="theme-bar slider-wrapper">
            <div id="slider" class="nivoSlider theme-bar">
                <a href="#"><img src="images/slide1.jpg" alt="" /></a>
                <img src="images/slide2.jpg" alt="" />
                <img src="images/slide3.jpg" alt="" />
                <img src="images/slide4.jpg" alt="" />
            </div>
       </div>

Here is my CSS (I have two CSS files linked to this page nivo-slider.css and bar.css for the Nivo Slider theme).

nivo-slider.css:

    .nivoSlider {
    position:relative;
    width:100%;
    height:auto;
    overflow: hidden;
}
.nivoSlider img {
    position:absolute;
    top:0px;
    left:0px;
    max-width: none;
}
.nivo-main-image {
    display: block !important;
    position: relative !important; 
    width: 100% !important;
}

/* If an image is wrapped in a link */
.nivoSlider a.nivo-imageLink {
    position:absolute;
    top:0px;
    left:0px;
    width:100%;
    height:100%;
    border:0;
    padding:0;
    margin:0;
    z-index:6;
    display:none;
}
/* The slices and boxes in the Slider */
.nivo-slice {
    display:block;
    position:absolute;
    z-index:5;
    height:100%;
    top:0;
}
.nivo-box {
    display:block;
    position:absolute;
    z-index:5;
    overflow:hidden;
}
.nivo-box img { display:block; }

/* Caption styles */
.nivo-caption {
    position:absolute;
    left:0px;
    bottom:0px;
    background:#000;
    color:#fff;
    width:100%;
    z-index:8;
    padding: 5px 10px;
    opacity: 0.8;
    overflow: hidden;
    display: none;
    -moz-opacity: 0.8;
    filter:alpha(opacity=8);
    -webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
    -moz-box-sizing: border-box;    /* Firefox, other Gecko */
    box-sizing: border-box;         /* Opera/IE 8+ */
}
.nivo-caption p {
    padding:5px;
    margin:0;
}
.nivo-caption a {
    display:inline !important;
}
.nivo-html-caption {
    display:none;
}
/* Direction nav styles (e.g. Next & Prev) */
.nivo-directionNav a {
    position:absolute;
    top:45%;
    z-index:9;
    cursor:pointer;
}
.nivo-prevNav {
    left:0px;
}
.nivo-nextNav {
    right:0px;
}
/* Control nav styles (e.g. 1,2,3...) */
.nivo-controlNav {
     position: absolute;
    left: 0;
    bottom: -41px;
    z-index: 10;
    width: 100%;
    height: 30px;
    text-align: center;
    padding: 5px 0;
    border-top: 1px solid #333;
    background: #333;
    background: -moz-linear-gradient(top,  #565656 0%, #333333 100%); /* FF3.6+ */

    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#565656', endColorstr='#333333',GradientType=0 ); /* IE6-9 */
    opacity: 0.5;
    -webkit-transition: all 200ms ease-in-out;
    -moz-transition: all 200ms ease-in-out;
    -o-transition: all 200ms ease-in-out;
    transition: all 200ms ease-in-out;
}
.theme-bar .nivo-controlNav {
    bottom: 0;
    opacity: 1;
}
.nivo-controlNav a {
    display:inline-block;
    width:22px;
    height:22px;
    background:url(bullets.png) no-repeat;
    text-indent:-9999px;
    border:0;
    margin: 5px 2px 0 2px;
    cursor: pointer;
}
.nivo-controlNav a.active {
    background-position:0 -22px;
}

Here is the other CSS file. bar.css:

Here is script that I used. It is the default script that comes the Nivo Slider Jquery Plugin, except I messed around with the settings a little bit. I am only going to show you the script that I edited because I am limited to 30000 characters:

    //Default settings
    $.fn.nivoSlider.defaults = {
        effect: 'fade',
        slices: 15,
        boxCols: 8,
        boxRows: 4,
        animSpeed: 550,
        pauseTime: 3500,
        startSlide: 0,
        directionNav: false,
        controlNav: true,
        controlNavThumbs: false,
        pauseOnHover: true,
        manualAdvance: false,
        prevText: 'Prev',
        nextText: 'Next',
        randomStart: false,
        beforeChange: function(){},
        afterChange: function(){},
        slideshowEnd: function(){},
        lastSlide: function(){},
        afterLoad: function(){}
    };

    $.fn._reverse = [].reverse;

})(jQuery);

Again, the problem is just that the image looks blown up and you can't see all of it. I tried setting the width for .nivoSlider class to the exact width of the image, but its still not working. Thanks for the help in advance!
And yes, I did activate the Jquery with this code:

<script type="text/javascript">
$(window).load(function() {
    $('#slider').nivoSlider();
});
</script>

Comment:
The images are sized the way I want them to be. I think its the div that wraps the slider, that has the problem. I just can't see why the images are like this. Normally the Nivo Slider resizes itself to fit the image, but its resizing my image to fit it instead.
