A new beta feature will soon be released on all wikis: The FileExporter. It allows exports of files from a local wiki to Wikimedia Commons, including their file history and page history. Which files can be exported is defined by each wiki's community: Please check your wiki's configuration file if you want to use this feature.
The FileExporter has already been a beta feature on mediawiki.org, meta.wikimedia, deWP, faWP, arWP, koWP and on wikisource.org. After some functionality was added, it's now becoming a beta feature on all wikis. Deployment is planned for January 16. More information can be found on the project page.
As always, feedback is highly appreciated. If you want to test the FileExporter, please activate it in your user preferences. The best place for feedback is the central talk page. Thank you from Wikimedia Deutschland's Technical Wishes project.
