您使用的静态模板标记错误。它应该用于您要在页面上使用的静态文件。例如链接到非用户上传的样式表、javascript 或图像。
有关更多信息,请参见此处:https : //docs.djangoproject.com/en/2.0/howto/static-files/
您正在尝试从模型中上传的文件中获取图片 - 可能由用户上传完成(或以非“静态”的方式完成)。这是通过媒体网址和媒体根设置处理的。请参见此处:https : //docs.djangoproject.com/en/2.0/topics/files/
获取图像的正确方法是:
<img src = "{{ software_page.image.url }}" alt = "Profile Picture"/>
