There's a helpful table here:
https://meta.wikimedia.org/wiki/EDP#Wikivoyage
which lists out which Wikivoyage wikis want local uploads enabled, and
which EDPs currently exist.
Remember, per our licensing policy, an EDP (basically a "fair use
policy") should be in place for wikis with local uploads. All freely
licensed files need to go to Commons.
Please help vet this table so we can adjust the configuration settings
accordingly.
The local thumbnails issue on
en.wikivoyage.org should be fixed now
and other wikis will follow shortly.
