I've come up with an actual image slider that you can use - jQuery is the only dependency. This code will dynamically handle any number of images you want in the carousel. Please let me know if you have any questions or if this helps at all.

The code that is commented out is for automatically sliding.

scripts.js 
$(function() {
    /****************************************
            Variables
    ****************************************/

    var $carousel = $(".carousel"); 

    /*
        Adding or removing images is as simple as updating
        this list.
    */
    var images = [
        "img/mustang.jpg",
        "img/hangar.jpg",
        "img/tron.jpg"
    ];



    /****************************************
            Event Handling
    ****************************************/

    $("button").click(function() {
        slide();
    });



    /****************************************
            Functions
    ****************************************/   

    function appendImages() {
        var $images = $(".carousel img");
        $images.remove();
        for (var i = 0; i < images.length; ++i) {
            var $image = $("<img>");
            $image.attr("src", images[i]);
            $image.css({
                "max-width": "100%",
                "position": "absolute"
            });
            if (i > 0) {
                $image.css("left", "100%");
            }
            $carousel.append($image);
        }
    }

    function complete() {
        var img = images.shift();
        images.push(img);
        appendImages();
        //setTimeout(slide, 2000);      
    }

    function slide() {
        var $images = $(".carousel img");
        $images.eq(0).animate({
            "left": "-100%"
        }, 1000);

        $images.eq(1).animate({
            "left": "0%"
        }, 1000, complete)
    }



    /****************************************
            Document On-load Actions
    ****************************************/

    appendImages(); 
    //setTimeout(slide, 2000);
});
main.css 
body {
    position: relative;
    overflow-x: hidden;
}

.carousel {
    width: 800px;
    height: 600px;
    margin: 0 auto;
    position: relative;
    overflow-x: hidden;
}

button {
    margin: 0 auto;
    margin-top: 50px;
    padding: 20px 40px;
    position: absolute;
    left: 50%;
    transform: translate(-50%, 0);  
}

Hi An,

This may not be the simplest image slider, but you're welcome to look at the code for my JavaScript carousel.

Hope this helps,

Cheers
