Personalization Settings Image

Basically, I added some background images as a joke, and I deleted them from my computer and changed my wallpaper back.

But it seems to have permantly cached these images, I even tried restarting and going to my appdata folder to see what I could find.

How exactly do I remove cached background images like this?
