You'll need to edit the file page (in this case, File:20171103193719_1.jpg). Copy/paste the Information template, and fill out the necessary fields (most importantly, source and license).

The tutorial, and specifically Step Four, gives step-by-step instructions about how to do this. If, after reading, there's something that's still unclear, feel free to ask.
