From Test-Scratch-Wiki
New images is a special page that lists recently added files as a gallery in reverse order, with creation date and time, current size, user who uploaded the file, and name of the uploaded file.
This feature is accessible at Special:NewImages. The page results are not adjustable using settings the Preferences.
This special page can be transcluded using {{Special:NewImages/50}}, with the first unnamed parameter specifying how many entries should be displayed.
