If you go back to Dalmatia's original post and click on the image link, you can see on the right side of the image there a space called "Categories" with Willy's name partially spelled out as "Will." Underneath that, the field has auto-populated to say "Images of Willy Tybur." That is where you add the character categories.

Just start typing in "Images of [insert character name]" and the field should auto-populate so you can just click on the one you want (don't forget continuity in cases like Mikasa who can have a manga/anime/Lost Girls appearance). If a character name doesn't auto-populate they either are very new or you spelled it wrong.
