Dear Patrick,
Sorry about my delay in getting to this image. So lets start at the beginning.
First, I looked at the embedded data and I've made a fairly good determination that it was not photo-shopped. All the factors within the image are consistant with an original image. However, the signs I see on the image indicate that perhaps it was scanned with a HP PhotoSmart scanner? Is that the case?
The original file was created back in 2007, so its an older file. Was it scanned from a picture, and did the original picture have the same effects on it?
If its chemical photograph (old style picture) then there is a possibility that something happened in the developing process. But, generally some form of spill or chemical imbalance during developing generally would reduce detail rather than expand it.
Without additional information I would have to say this is inconclusive. And I would look at supporting evidence from the time when this was taken to support that it may be paranormal in nature. Were there any EVP's, any kind of other events that took place at the same time? Anything visually happening at the time the picture was snapped?
I've expanded the area of interest. I found that the image is most pronounced in the lower frequencies (red) and as you sweet to the higher frequencies the image tends to blurr and fade into obscurity. This is in keeping with other paranormal photography, where entities tend to manifest themselves more in the lower or infrared spectrum.
I've enhanced the area of interest, applying a color curve to bring out the detail in the lower frequencies and reduce the noise from the upper frequencies. Also I've brought up the contrast and balanced the brightness.
