请参考我在CodePen 上的代码，您需要编写文件读取方法进行读取和查看，参考link

<input type="file" name="image-file" id="imgupload" style="opacity: 0;">
  <a href="#" onclick="$('#imgupload').trigger('click'); return false;">
          <div class="img-thumbnail img-circle">
            <div style="position: relative; padding: 0; cursor: pointer;">
              <img class="img-circle" style="width: 140px; height: 140px;" >
              <span style="position: absolute; color: red; opacity: 0;">  <span>UPLOAD</span>
                        <!-- The file is stored here. -->
                        </span>
            </div></div>
  </a>
