If you used an intermediate source, then both the original and intermediate sources should be listed on the file's description. And no, categories don't mean the articles that you want to use the file on. It means adding the file to one of the categories listed on Category:Images. In this case, a file that's based on an episode should be categorised under a specific episode category, namely Category:S2E16 Screenshots. You can add categories via the "Add categories" button at the bottom of the page or via the editor.

To add the image to the article, go to http://swordartonline.wikia.com/wiki/Outside_System_Skill?action=edit&section=2, select source mode and the replace the old file name with the new one.
