MediaWiki:External image whitelist

#

# Put regular expression fragments (just the part that goes between the //) below.
# These will be matched with the URLs of external (hotlinked) images which will be
# displayed as imaged if a match is found.
#
# Lines beginning with # are treated as comments
# Fragments, as with URLs, are case insensitive
# --------------------------------------------------------------------------------
# !!! Security Warning !!!
# Make sure all fragments have a / after their domain name
# otherwise other domains can still match these fragments
# 
# Bad:
#   wikipedia\.org           -> matches wikipedia.org.example.com
#
# Good:
#   wikipedia\.org/          -> trailing backslash
#   wikimedia\.org/wikipedia -> does not need a trailing backslash due to the
#                               presence of the path
