A dead simple jQuery slideshow / carousel component that allows for looping infinitely through a group of background images with a fadeIn / fadeOut transition effect based on CSS3 transitions.

How to use it:

1. Add background images to slides and the wrap them together with counter and navigation into a container.

<div class="fadeImgs">

  <span class="thumb active" style="background-image: url('1.jpg');"></span>
  <span class="thumb" style="background-image: url('2.jpg')"></span>
  <span class="thumb" style="background-image: url('3.jpg')"></span>
  <span class="thumb" style="background-image: url('4.jpg')"></span>
  <span class="thumb" style="background-image: url('5.jpg')"></span>

  <div class="photoCount">5</div>
  <div class="photoNext"></div>
  <div class="photoPrev"></div>

</div>

2. Add the following carousel styles into your webpage.

.fadeImgs {
  width: 600px;
  height: 450px;
  position: absolute;
  margin: -4px 0 0 -10px;
}

.fadeImgs .thumb {
  width: 600px;
  height: 450px;
  background-size: cover;
  background-position: center center;
  background-repeat: no-repeat;
  position: absolute;
  top: 0;
  opacity: 0;
  transition: opacity .25s ease-in-out;
}

.fadeImgs .thumb.active {
  opacity: 1;
  transition: opacity .25s ease-in-out;
}

.fadeImgs .photoCount {
  position: absolute;
  top: 0;
  left: 0;
  padding: 3px 8px 3px 8px;
  background-color: rgba(0, 0, 0, 0.5);
  color: #fff;
  font-weight: bold;
  font-size: 12px;
  overflow: hidden;
  z-index: 5;
}

.fadeImgs .photoNext {
  position: absolute;
  bottom: 188px;
  right: 10px;
  background-image: url(right-thin.png);
  width: 30px;
  height: 74px;
  opacity: .7;
  transition: opacity .25s ease-in-out;
  z-index: 5;
  cursor: pointer;
}

.fadeImgs .photoPrev {
  position: absolute;
  bottom: 188px;
  left: 10px;
  background-image: url(left-thin.png);
  width: 30px;
  height: 74px;
  opacity: .7;
  transition: opacity .25s ease-in-out;
  z-index: 5;
  cursor: pointer;
}

.fadeImgs .photoNext:hover { opacity: 1; }

.fadeImgs .photoPrev:hover { opacity: 1; }

3. Include the latest version of jQuery JavaScript library at the bottom of the webpage.

<script src="//code.jquery.com/jquery-latest.min.js"></script>

4. The core JavaScript (jQuery script) to active the carousel.

$( document ).ready(function() {
  $( ".photoNext" ).click(function( event ) {
    event.preventDefault();
    $(this).siblings( ".active" ).addClass( "fadeFrom" );
    $( ".fadeFrom" ).nextOrFirst('.thumb').addClass( "fadeTo" );
    $( ".fadeFrom" ).removeClass( "active" );
    $( ".fadeFrom" ).removeClass( "fadeFrom" );
    $( ".fadeTo" ).addClass( "active" );
    $( ".fadeTo" ).removeClass( "fadeTo" );
  });
  $( ".photoPrev" ).click(function( event ) {
    event.preventDefault();
    $(this).siblings( ".active" ).addClass( "fadeFrom" );
    $( ".fadeFrom" ).prevOrLast('.thumb').addClass( "fadeTo" );
    $( ".fadeFrom" ).removeClass( "active" );
    $( ".fadeFrom" ).removeClass( "fadeFrom" );
    $( ".fadeTo" ).addClass( "active" );
    $( ".fadeTo" ).removeClass( "fadeTo" );
  });
});

$.fn.nextOrFirst = function(selector){
    var next = this.next(selector);
    return (next.length) ? next : this.prevAll(selector).last();
};

$.fn.prevOrLast = function(selector){
    var prev = this.prev(selector);
    return (prev.length) ? prev : this.nextAll(selector).last();
};
