If someone uploads a file for a specific page via mobile web, it gets uploaded to commons with upload summary "Added image for use on page"
It would be cool (imo) if the upload summary mentioned which page. There is of course global usage, but sometimes the image gets removed from the page, and its good to keep a record of the original context for the upload.
Ideally something like: "Added image for use on page [[fr:Foo.jpg]]" (I'm assuming only wikipedia has this feature. Otherwise the interwiki prefixes could get tricky to implement right)
