我正在开发一个在线书店应用程序。我有一个图书详细信息页面，它在一个表中显示图书信息，包括图书封面图像。我遇到了一个问题，当我运行服务器时，图像显示正确，但是团队成员无法在从Github拉取我的代码后显示图像。
所有书籍模板：

{%  extends 'bookstore/main.html' %}
{% load crispy_forms_tags %}
{% load static %}
from .models import Product

{% block content %}
  <div class="container">  
      <p>
        <h1 style="text-align:center;color:green;"> 
            GeekText Complete List of Books<br>
        </h1>

        <h3 style="text-align:center;color:green;">
            Click the Book Name for More Details
        </h3>
      </p>
      
    <div class="container">
      <div class="col-md-12">
        <table id="myTable" class="table table-striped tablesorter">

        </table>
        {% endblock %}
