Spirit photography or detailed tricks of the light?

My parents have just put their house up for sale and yesterday brought round the estate agent descriptive, with photos, to show us. They’d already spotted some very unusual elements contained within the main photograph (above). I’ve asked them to see if they can wrangle copies of the original photos from the estate agent but for the time being I’ve scanned the paper version for you to see, although the resolution degrades with each expanded segment.
I can tell you that when looking at the original photo what are known as ‘artefacts’ in the image appear very sharp indeed. What you need to focus on are the two windows to the right of the image, the upstairs bedroom and the living room:
You should be immediately able to see something odd in each window, but if not here’s a blown-up image:
And here’s another, an even greater expansion:
You can obtain bigger versions of these from my Flickr photostream.
What do you see?
The artefact in the upstairs windows is considerably easier to make out on the original printed photograph. For reasons unknown to me, the transfer from page to scan has stripped it of its clarity. It appears to be a woman standing in the middle of the bedroom. It is definitely not my mother, as the figure is a completely different shape.
There are two much more pronounced artefacts in the living room window. Both appear to be men, the one on the left I think is wearing a hat and a scarf. The figure on the right is wearing a bow-tie and a suit.
I find it fascinating that these men appear to be black-and-white images. I readily admit they appear scanned and added into the photograph after it was taken, but I can assure you they were not. I suppose you could imagine the estate agent, in some wildly uncharacteristically imaginative moment, decided to fake a spirit photograph. But I think that’s really pushing it. My parents don’t know how to use computers for anything, let alone advanced image manipulation in the likes of Photoshop.
More to the point, my mother recognises the man on the right. She says it is her grandfather, my great-grandfather.
My parents’ house has often been a focus for strange phenomena, in part I think because of the sensitivity to such things several members of my family share. I can only wonder as to why the spirits—if spirits they were—decided to put in an appearance on the estate agent photograph.
