Using the URLconf defined in config.urls, Django tried these URL patterns, in this order:

1. mng/
2. about/guidance [name='about/guidance']
3. about/institution [name='about/institution']
4. about/members [name='about/members']
5. letter [name='letter/list']
6. activity [name='activity/index']
7. photo/album [name='photo/album']
8. [name='index']
9. ^static/(?P<path>.*)$
10. ^media/(?P<path>.*)$

The current path, letter/letter/o/7aea52b433b8a2e554820c39e94f4d5e.JPG, didn’t match any of these.

You’re seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
