Try going directly to the image http://attackontitan.wikia.com/wiki/File:Xavi_hears_Sharle_is_gone.png and click on the Edit button to take yourself into the editor. Then copy and paste the file information template into the editor.

Make sure you're using the Source Editor, not the Visual Editor, so you can paste the code directly in the editing field. If you normally use the Visual Editor by default you will see a Source tab that will let you switch over to directly editing the code (it's in the screenshot Dalmatia linked).

Paste the template into the Source tab and fill in the Description, Source, Pages, and Resolution fields. (The rest should auto-populate based on what you put in the Source field.) Then save it like you would any other idea and you should be done.
