Well, whoever posted the pic linked from my site even went so far as to copy and paste what I wrote about the pic. Personally I think it's just a pic of the LOTR Black Riders without all the effects that make them look otherworldy. Even the background in the image looks rather like Weathertop, but it's hard to tell.. - that's exactly what I wrote on my site about the pic.

And for the record, I'd never even heard of this site until Lumos, from here, commented on my article telling me where the pic really came from - which I appreciated and have edited my article to give proper credit to Dumbledore for creating a cool pic. And I've enjoyed looking around here, snitchseeker's really well done
