下一张和上一张传递图片

Question

我正在使用以下具有两种模式的代码 “模态画廊”显示模态中的放大图像 当您删除图像时，请单击“ modalgconfirmedelete”。 我希望“ modalgallery”包含下一个和上一个按钮，但是我做不到。 谢谢你的帮助

modalgallery.js

$(function() {
$('.pop').on('click', function() {
    $('.imagepreview').attr('src', $(this).attr('data-img-url'));
    $(this).next('.imagemodal').modal('show');   
});     
});

modalconfirmedelete.js

$(function() {
    $('.pop2').on('click', function() {
   $(this).closest(".imagemodal").next(".delete").modal('show');   
    });     
 });

perfil.html

  {% for photo in photos %}


  <a class="pop" href="#"  data-img-url="{{ photo.file.large.url}}"><img src="{{ photo.file.medium.url}}"class="img-thumbnail" width="200" height="200"> </a>

  <!-- Modal Gallery-->
  <div class="modal fade imagemodal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
        <div class="modal-dialog modal-lg">
              <div class="modal-content">

              <img src="" class="imagepreview" style="width: 100%;" >
              <a class="pop2" href="#" ><img src="{% static 'svg/delete.svg' %}" width="20" height="20" alt="">Deletar </a>
