That would be a mistake on my end. Despite the fact that the image was actually being used, it still appeared in the UnusedFiles report and I marked most images there for deletion aside from a few I added into some of the gallery articles. ThePokémonGamer should be able to use Special:Undelete to restore the image.
Another thing, can you please give a proper, legitimate name to all the images you upload here? Something like File:Missing Community Header.jpeg would be a lot more fitting than File:E991067B-AE66-43C1-9529-772C7094C4AE.jpeg. It just helps keep things organized.
I uploaded it right from my iPad using the Upload Image function from the Message Wall, that doesn't give me the option to name it (I should've used Special:Upload in retrospect). I'll replace it right now.
