Uploading images use Django Ckeditor --getting server error(500)

Uploading images use Django Ckeditor --getting server error(500)

I have been struggling for the problem for two days. Unfortunately, i still have no idea to solve it due to my poor knowledge. So i have to come here asking for help. Very appreciate ！

I want to write a website as my blog and use Django to implement it. To develop this website, i have to use rich text editor, so i use CKeditor on admin panel. Here is the link of Ckeditor source code on github. https://github.com/django-ckeditor/django-ckeditor

To upload images using ckeditor widget , i edited this file../static/ckeditor/ckeditor/plugins/image/di alogs/image.js so it can display the images upload button.

id:"Upload",hidden:!0

I also added upload url in config.js. After that, i set routing in the urls.py and added a view function in views.py. Everything was ok on my computer. however, after i deployed it to website server i got server error(500) during uploading a image by ckeditor . Ckeditor widget can not return the urls but i can find the images on server which i uploaded by ckeditor.

$:~/sites/www/source$ ls ../media/images/
