User blog comment:Hunnie Bunn/Hidden Pottermore Images/@comment-3095064-20120919213650

It's actually recently come to my attention (thanks to the anon here) that these images aren't unused. If you favourite a spell page, the wand motion image thing is used to illustrate it on the favourites page. I'll proceed to add them to the respective pages (I know I uploaded Switching Spells and Killing Curse a while back).
