MediaViewer displays images with associated metadata on top of wiki pages. Currently it does not display the file name in an easily copy-pastable form, which is a frequent pain point for experienced editors.
Please add the file name to the information list that can be seen when you scroll down to the metadata panel. It should be in the form "File:Foo bar.jpg" - namespace prefix (always in English) included, extension included, spaces instead of underscores. This is T76680 in Wikimedia's issue tracker; you can find the mockup and icon there.
Students are required to read Wikimedia's general instructions first.
