Html Lightbox2在全屏图像集的末尾添加了一个额外的图像

我刚刚注意到Lightbox2（）在全屏版本的图像末尾复制或添加额外的图像，其他一切都正常。查看时，我单击下一个图像的下一个图像箭头，当我到达最后一个图像（image_5.jpg）时，不应该有更多的“下一个”按钮/选项，但如果我单击它，它会再次显示最后一个图像

<div class="galleryContainer">
  <div class="gallery_image">
    <a class="example-image-link" href="./images/studio/image_1.jpg" data-lightbox="studio-set"><img class="studio-image" src="./images/studio/image_1.jpg" alt=""/>
    <a class="example-image-link" href="./images/studio/image_2.jpg" data-lightbox="studio-set"><img class="studio-image" src="./images/studio/image_2.jpg" alt=""/>
    <a class="example-image-link" href="./images/studio/image_3.jpg" data-lightbox="studio-set"><img class="studio-image" src="./images/studio/image_3.jpg" alt=""/>
    <a class="example-image-link" href="./images/studio/image_4.jpg" data-lightbox="studio-set"><img class="studio-image" src="./images/studio/image_4.jpg" alt=""/>
    <a class="example-image-link" href="./images/studio/image_5.jpg" data-lightbox="studio-set"><img class="studio-image" src="./images/studio/image_5.jpg" alt=""/>
  </div>
