Thanks for the link, Alicat.
First, I have to admit…I spent about a minute just trying to pronounce "Gloucestershire." Doesn't exactly roll off the tongue, does it? 
The picture is somewhat interesting. What I don't like is found in this quote:
"I checked again and looked in the doorway but I could see nothing."
I'm not a big fan of a normal camera showing something in a picture that the naked eye doesn't see. That, in itself, sends up a big red flag for me.
I did love the second link. I like the 360 thing and I really like being able to zoom in and out and move the picture around. Dust playing tricks in light comes to mind when looking close up at the image. Notice the light above the figure (looks like smoke). It's either…ecto-plasmic mist…*cough, cough*…or light in which the dust hadn't risen to that height. No dust…it just looks like light. Add dust…you get something pretty interesting.
Also…you've got that big window just to the left of the image. The museum/house, from Alicat's last link, was at least owned in 1785. I couldn't find the actual year that it was built, but safe to say probably before 1785. That being said, I would be interested in the glass in the actual window. Having been to Europe many times, I noticed that many older buildings have insanely thick glass. And even if it's not thick, some of that older glass isn't quite as "see-through" as we're accustomed to in the states. Light does all kinds of tricky things when coming through older glass.
Overall, I think the image is pretty cool. Do I believe that it's paranormal? I'm going to lean towards no.
