Including a Django app's url.py is resulting in a 404
Remove the $ from the regex of main urls.py
urlpatterns = patterns('', (r'^gallery/', include('mysite.gallery.urls')),)You don't need gallery in the included Urlconf.
urlpatterns = patterns('', (r'^browse/$', 'mysite.gallery.views.browse'), (r'^photo/$', 'mysite.gallery.views.photo'),)Read the django docs for more information
Note that the regular expressions in this example don't have a
$(end-of-string match character) but do include a trailing slash. Whenever Django encountersinclude(), it chops off whatever part of the URL matched up to that point and sends the remaining string to the included URLconf for further processing.
