Problem with slideshow; unexpected refresh

Hi, I am designing a slideshow with jQuery (very simple, no timer or transitions, at least not yet). I'm stacking all the images on top of each other and revealing them by moving an id from image to image, which sets the z-index really high. The problem I'm finding is that every time I run it, my website unexpectedly refreshes, and the z-index goes back to the first image.

<div class="comic group">
            <img id="top-image" src="img/page1.jpg">
            <img src="img/page2.jpg">
            <img src="img/page3.jpg">
            <img src="img/page4.jpg">

        </div>

    #slideshow {
        width: 700px;
        height: 935px;
        margin: 0 auto;
        position: relative;
    }
    .slide {
        width: 700px;
        height: 935px;
        position: absolute;
        left: 0;
        top: 0;
    }

    .comic {
        width: 100%;
    }
    .comic img {
        width: 50%;
        float: left;
        padding: 10px 2%;
    }

    .comic img {
        width: 50%;
        float: left;
        padding: ;
    }

    .arrow {
        z-index: 200;
        position: absolute;
        font-size: 3em;
        background: rgba(255, 255, 255, .5);
        padding: 0 15px 5px;
        top: 10px;
        border-radius: 5px;
    }
    #left {
        left: 10px;
    }
    #right {
        right: 10px;
    }

    #top-image {
        z-index: 100;
    }

}

$(".comic").attr('id', 'slideshow');
$("#slideshow").removeClass("comic");
$("#slideshow img").addClass("slide");
$("#slideshow").append('<p class="arrow" id="left"><a href="">&lt;</a></p>');
$("#slideshow").append('<p class="arrow" id="right"><a href="">&gt;</a></p>');

$("#right").click(function() {
    $currentImage = $("#top-image");
    $currentImage.next().attr('id', 'top-image');
    $currentImage.removeAttr('id', 'top-image');
});

Even blank link like 

<a href="">

is actually calling a new page ie refresh. So each time the arrow is clicked its refreshing your page. Prevent default behavior or change it to a button instead.
