You can now use media files from your wiki inside of Wikibase.
We created a new data type for Wikibase that enables working with media files defined on your wiki. Previously Wikibase only supported working with media files from Wikimedia Commons. The new data type, called “Media file” works exactly like “Commons media file”, but then for your local media files. The “Media file” data type is available via our new extension Wikibase Local Media.
