A ghost hunter believes he has captured the spirit of a female coal sorter taking a nighttime walk through a former mine.
Jimmy Devlin, 44, says he came across the apparition during a paranormal investigation in April.
He took pictures of the eerie sight at Lady Victoria pit in Newtongrange, Midlothian, which is now home to Scotland's National Mining Museum.
He said: "I have very rarely shared any of my work, more because of ridicule and cyber abuse from closed minded individuals.
"I do however feel I would like to share this image I captured whilst taking random shots before my investigation began.
"It was taken whilst standing on one of the high walkways that run over the old bogey tracks that surround the pit head.
"It appears to me, to be that of a woman, dressed in a long flowing skirt, blouse and possibly her hair tied up or wearing a headscarf.”
Indeed the museum’s website features recreations of women sorting coal in the mines wearing similar garb to that of the other-worldly spectre.
Devlin continued: "I have been visiting the mining museum for six or seven years for public events.
"But this was one I wanted to do privately. I went along with two or three friends who do this on a regular basis.
"But we split up and I was completely on my own when that happened. We keep in touch with walkie-talkies.
"This was a good capture. With the size of the place we have only really just scratched the surface."
Devlin is already planning to go back to the site, which he says "never disappoints" when it comes to ghost hunting.
He said: "Some people find it scary, but it's my kind of thing. I enjoy doing it. When you get stuff like that it actually keeps you going.
"As sometimes it can be quite frustrating, it's like fishing sometimes.
"Although the mining museum never usually disappoints. Something tends to happen when we are there.
"I will be going back there for Halloween weekend.
"I have conducted many investigations there, but given its size I feel I have only scratched the surface.
"I've also held public paranormal events here, where members of the public get the chance to practice investigating with my equipment, and just as importantly using their senses in the dark.
"Two years ago I brought along (TV Psychic) Derek Acorah, he picked up on a washer-woman called Mary.
"She had been seen and heard previously in different parts of the museum, and this photograph further proves that this museum still has its visitors from the past."
The mining museum's marketing manager Gillian Rankin said the sighting was not a surprise "at all", adding: "Quite a lot of our employees here have heard things and felt things.
"We do have ghost events here. For the family, and overnight events for the more experienced paranormal people. Jimmy comes with his full equipment.
"There are definitely ghosts in the museum. We have always heard footsteps and doors opening on their own. It's quite scary, but very interesting. Well, it's not scary really. It's a friendly energy. No sinister feelings at all.
"It's an old colliery so there is bound to be something there.
"We have two events at Halloween. A family ghost tour in the evening with ghost stories about the museum and the local area. As well as an overnight event.
"I would encourage people to come along."
